Synthesis and characterization of a new Schiff-base derivative as an optical nickel (II) chemosensor and its antimicrobial activity

A receptor in the form of (E)-(4-(thiophen-2-yl)phenyl)-N-(4H-1,2,4-triazol-4-yl)methanimine Schiff base L was synthesized through the reaction of 4-amino-4H-1,2,4-triazol with 4-(2-thiazol)benzaldehyde. The resulting Schiff base L was characterized by physicochemical techniques such as elemental analysis, UV-vis, Fourier transform infrared (FT-IR), mass spectrometry, and NMR. The Schiff base L receptor was exploited as an optical chemical sensor for nickel (II) metallic cationic concentration determination. The chemosensor demonstrated a consistent absorption intensity change at 385 nm related to the nickel (II) concentration in the range of 0–50 µM with a calibration sensitivity of 0.0052 Abs/µM in addition to calibration linearity (R2 = 0.9839) and possessing a response time of less than 5 mins. Other cations, Fe2 + Cu2+, Co2+, Zn2+, Cd2+, Mn2+, Mg2+, Cr2 + Ag+, Ca2+, Al3+, Li+, Na+, K+, Nd3+, Dy3+, Sm3 …

Synthesis, characterization, and DFT calculations of a new sulfamethoxazole schiff base and its metal complexes

A new Schiff base, 4-((1E,2E)-3-(furan-2-yl)allylidene)amino)-N-(5-methylisoxazol-3-yl) benzene-sulfonamide (L), was synthesized by thermal condensation of 3-(2-furyl)acrolein and sulfamethoxazole (SMX), and the furan Schiff base (L) was converted to a phenol Schiff base (L’) according to the Diels–Alder [4 + 2] cycloaddition reaction and studied experimentally. The structural and spectroscopic properties of the Schiff base were also corroborated by utilizing density functional theory (DFT) calculations. Furthermore, a series of lanthanide and transition metal complexes of the Schiff base were synthesized from the nitrate salts of Gd, Sm, Nd, and Zn (L1, L2, L3, and L4), respectively. Various spectroscopic studies confirmed the chemical structures of the Schiff-base ligand and its complexes. Based on the spectral studies, a nine-coordinated geometry was assigned to the lanthanide complexes and a six-coordinated geometry to the zinc complex. The elemental analysis data confirmed the suggested structure of the metal complexes, and the TGA studies confirmed the presence of one coordinated water molecule in the lanthanide complexes and one crystalline water molecule in the zinc complex; in addition, the conductivity showed the neutral nature of the complexes. Therefore, it is suggested that the ligand acts as a bidentate through coordinates to each metal atom by the isoxazole nitrogen and oxygen atoms of the sulfur dioxide moiety of the SMX based on FTIR studies. The ligand and its complexes were tested for their anti-inflammatory, anti-hemolytic, and antioxidant activities by various colorimetric methods. These complexes were found to …

A Schiff base ligand prepared from amino acid (L-Histidine) and salicylaldehyde (L1), 1, 10 phenanthroline (L2) and its transition metal complexes of general formula [ML1L2](where M= Co (II), Cu (II), Zn (II), and Cd (II)) has been synthesized and tested for in vitro antimicrobial study against harmful bacterial strains Escherichia coli (gram negative bacteria), Bacillus subtilis, Staphylococcus aureus (gram positive bacteria), and fungal organisms Aspergillus avus, Rhizophus stolonifer and Mucor ellipsoideus respectively via agarwell diffusion technique. The larvicidal activity of the complexes was tested against Culex quinquefasciatus mosquito. The synthesized complexes exhibited excellent antioxidant properties both by DPPH and Hydrogen peroxide assays. Analytical and spectroscopic techniques such as UV-Visible, FTIR, SEM, NMR, and HRMS were used to characterize the produced Schiff base metal complexes. TGA-DTA analysis was used to investigate the thermal stability of the complexes. The redox characteristics of the complexes were examined using cyclic voltammetry. Cd (II) complex shows the maximum zone of inhibition values 20 mm and 21 mm for S. aureus, and M. ellipsoideus, respectively. Among the synthesized complexes, Cd (II) complex showed highest antimicrobial, larvicidal activity and very good antioxidant property.

A single-crystal X-ray diffraction investigation verified the chemical structure of (E)-ethyl-4-(5‑bromo-2-hydroxybenzylidene amino) benzoate (1). Schiff base 1 crystallizes in the triclinic space group P 1¯ with unit cell dimensions of a= 5.961 (2), b= 7.499 (3), c= 17.112 (6) Å and unit cell angles of α= 95.565 (12), β= 94.192 (13), γ= 104.689 (13)°. Density functional theory (DFT) calculations utilizing the B3LYP level of theory and the 6–31+ G (d, p) basis set have validated the reported experimental geometries and spectroscopic data (UV–vis, FT-IR, 1 H NMR) for 1 and 2-((E)-(4H-1, 2, 4-triazole-4-ylimino) methyl)-4-bromophenol (2), whereby Schiff base 2 corresponds to a literature known compound.

Synthesis, chemical and physical properties of lanthanide (III)(Nd, Gd, Tb) complexes derived from (E)-ethyl 4-(2-hydroxybenzylideneamino) benzoate

The 1:2 reaction between Ln(NO3)3·6H2O (1) (Ln = Nd (a), Gd (b) or Tb (c)) and ((E)-ethyl 4-((2-hydroxybenzylidene)amino)benzoate) (LN,OH) in ethanol has provided access to the complexes [LnIII(LNH,O)2(NO3)3(H2O)] (2a–c) in good yield. The isomorphous structures of 2a–c have been determined by single-crystal X-ray crystallography. The LnIII ions in 2a–c are coordinated by 9 oxygen atoms: two from the phenolate oxygen atoms of the Schiff bases, six from three chelating nitrato groups and one aqua ligand. The ligands LN,OH behave as monodentate phenolate O–donors, whereby an additional hydrogen atom is bonded to the imino nitrogen atom, resulting in a formally neutral ligand that adopts an exceptionally unusual coordination mode engaging in the zwitterionic form. The nine donor atoms that define the coordination polyhedra surrounding the LnIII ion are best described as capped square …

Ethyl4-(2-hydroxy-benzylideneamino) benzoate Schiff base (C16H15NO3), were synthesized and the structure was studied against the bases of X-ray, UV, visible, elemental analysis, 1 HNMR, IR and Mass spectroscopy. The crystal structure of the nickel complex has been determined by single crystal X-ray conformed the molecule, which indicate the compound is crystalline in the monoclinic C2/c with a= 16.0916 (5) Å, b= 6.0315 (2) Å, c= 29.0072 (10) Å, α= 90.00, β= 101.856 (2), γ= 90.00, V= 2755.3 (2) Å3 and Z= 8. Because of intra-molecular hydrogen bond involving the O atom of hydroxy group and N atom of azomethine group; the two benzene rings and azomethine group are practically coplanar. The Cobalt complex was prepared; the structure was characterized in the bases of IR spectra, elemental analysis, UV-visible, and conductance measurements. Also, the biological activity of both Schiff base and its Cobalt complex show that they are biologically active.INTRODUCTION: Schiff bases, which have an azomethine (imine) group (-C= N-) are usually prepared by condensation of a primary amine with an active carbonyl compound usually aldehyde or ketone 1. Schiff bases as chelating agents (ligands) in the field of coordination chemistry and their metal complexes are of great interest for many years; because O, N, and S atoms play a vital role at the active sites of numerous metallobiomolecules in the coordination chemistry of d-block elements 2 in addition of their biological applications as anticancer, antimicrobial 3, antifungal, antibacterial, and antiviral agents 4.
