Tridentate Schiff Base

The title complex was isolated as a red solid from the reaction of 4-(salicylaldiminato)antipyrine, HL, and cobalt (II) acetate in ethanol. The complex has been characterized by elemental analysis, FTIR, UV-Vis, and X-ray single crystal diffraction. Two crystallographically different cationic units, A and B, of the title complex are found. Both units are essentially isostructural; nevertheless, small differences exist between them. Both units contain four cobalt atoms arranged at the corners of distorted cubane-like core alternatively with phenoxy oxygen of the Schiff base. In both cases, one cobalt binds to three coordinated sites from the corresponding tridentate Schiff base ligand, and the fourth one was bonded by the acetate oxygen, and the fifth and the sixth donor sites come from the phenolate oxygen of another Schiff base ligand.

A aroylhydrazone Schiff-base ligand (1, 4-Bis(2’-formylphenyl)-1,4-dioxabutane isonicotinoylhydrazone) and its Zn (II) complex were synthesized by hydrothermal method. The ligand was characterized by IR spectrum, MS spectrum and X-ray single crystal diffraction analysis. The luminescent properties of the ligand and Zn (II) complex material have been investigated in solid and in organic solvents. The results show that the ligand has strong luminescent emission at ca. 454 nm and the fluorescence of Zn (II) complex is very weak.
