In order to obtain molecular Ce(III) complexes which emit red light by f–d transitions the azolyl-substituted thiophenolates were used as the ligands. The thiophenolate Ce(III) complexes were synthesized by the reaction of Ce[N(SiMe3)2]3 with respective thiophenols 2-(2′-mercaptophenyl)benzimidazole (H(NSN)), 2-(2′-mercaptophenyl)benzoxazole (H(OSN)) and 2-(2′-mercaptophenyl)benzothiazole (H(SSN))

The synthesis and antimicrobial activity of palladium(II) and platinum(II) complexes derived from heterocyclic bidentate ligands, namely 2-(2′-aminophenyl)benzoxazole [L1H2], 2-(2′-hydroxyphenyl)benzoxazole [L2H], and 2-(2′-mercaptophenyl)benzoxazole [L3H], are reported here. These complexes have been characterized by elemental analyses, molecular weight determinations, conductance measurements, infrared

photophysical properties of Gd and Yb compounds were studied both in solution and in the solid state. The fluorescence spectra of the compounds in solution display the bands of the keto and enol forms of the ligands. No energy transfer from the organic part to Yb3+ has been detected in solutions of both Yb complexes, whereas in solids an intense metal-centered emission in the near infrared region was
A method for making metal (8-quinolinolate) complexes from air and moisture stable reagents is described. For example, the making of aluminum tris(quinolinolates), such as tris(8-hydroxyquinolinato), from aluminum (III) carboxylates, such as aluminum lactate and aluminum stearate, is described. Examples of bis and tris metal (8-quinolinolates) as well as single and mixed ligand complexes are given.
