✦ Synopsis

A novel supramolecular mixed ligand complex of formula [Co(Phmal)(Him) 4 ] (Phmal D phenylmalonate, Him D imidazole) has been synthesized and characterized by FT-IR spectroscopy, thermogravimetric analysis (TG), UV-Vis spectra. X-ray crystallographic studies of the complex reveal that the cobalt atom exhibits a distorted octahedral geometry being coordinated by four nitrogen atoms of Him ligands, two oxygen atoms from the phenylmalonate ligand. The intramolecular C-H, interaction exists in the title complex. The three dimensional supramolecular network is constructed from the strong intermolecular N-H,O hydrogen bonds.
