The aim of the present study is to synthesize the oxovanadium complex of the V3+ ion with isatin sciff bases. Spectroscopic methods have been used to confirm these models of complexation and to understand the structures of the species formed in methanolic solution. We also have isolated a complex of Vanadium (III) with isatin schiff bases in the solid phase.

In the title compound, [Co(NCS)(2)(C(11)H(13)NO(2))(2)], a mononuclear Schiff base cobalt(II) complex, the Co atom is six-coordinated by four O atoms from two Schiff base ligands, and by two N atoms from two thio-cyanate ligands, forming a distorted octa-hedral geometry. The central Co atom lies on a twofold rotation axis. An intramolecular N-H⋯O hydrogen bond is present.

In the title complex, [Co(NCS)(2)(C(13)H(11)N(3)O)(2)], the Co(II) centre adopts a distorted octa-hedral coordination geometry with two cis-bidentate Schiff base ligands and two cis thio-cyanate ligands. The Schiff base ligand coordinates via the imine N and pyridine N atoms. The Co(II) atom lies on a crystallographic twofold rotational axis. Non-classical inter-molecular C-H⋯O hydrogen bonds l...

A series of symmetric multidentate Schiff base ligands 1–13 based on the N‚N′-4‚4′-ethylenebiphenylbis-3-methoxysalicylideneimine for used to bind various transition metals detection of K, AgI‚ CuII, Sr II Co II and NiII at trace levels in real-world samples has been synthesized purified and their structures was characterized.

Potentially tridentate, phosphine-containing Schiff bases with P,N,O and P,N,P donor sets have been prepared from 2-(diphenylphosphino)benzaldehyde, salicylaldehyde, 2-aminophenol 2-((diphenylphosphino)phenyl)methylamine reacted (NEt4)2[Re(CO)3Br3] in methanol. Deprotonation the formation of neutral [Re(CO)3(L)] complexes tridentate coordination has obtained for salicylidene derivatives, while ...

The mixed Co(II)/Ni(II) complex, [Co2.67Ni1.33L₄(CH₃COO)₂][BPh₄]₂·0.75H₂O where HL = 4-(salicylaldimine)antipyrine, was isolated as an orange solid from the reaction of 4-(salicylaldimine)antipyrine, with mixed cobalt(II) acetate and nickel(II) acetate in ethanol. The complex was characterized by Frustrated Total Internal Reflection (FTIR), UltraViolet Visible spectroscopy (UV-Vis), X-ray singl...

Many Organothallium Compounds have been used in medicine, industry and antibacterial activity. Optical properties are among the most fascinating and useful properties of many complexes and have been extensively studied using a variety of optical spectroscopic techniques. A basic understanding of the optical properties and related spectroscopic techniques is essential for characterization about ...

In the title compound, [Cd(NCS)(2)(C(11)H(17)N(3))](n), the Cd(II) atom is octa-hedrally coordinated by the N,N',N''-tridentate Schiff base ligand and one terminal thio-cyanate N atom. Two trans-N:S-bridging thio-cyanates complete the N(5)S donor set around the Cd atom. In the crystal, adjacent Cd(II) ions are linked by the thio-cyanate N:S-bridges into polymeric chains along the c axis.

In the mononuclear title complex, [ZnCl2(C15H16N4O)], the Zn(II) cation is five-coordinated in a strongly distorted square-pyramidal environment by two Cl(-) anions and a neutral tridentate Schiff base ligand. The Zn(II) cation is chelated by the carbonyl O atom, the imine N atom and the pyridine N atom, which causes a slight loss of planarity for the ligand; the dihedral angle between the arom...
