SYNTHESIS, CRYSTAL STRUCTURE AND FLUORESCENT PROPERTIES OF A NEW MONOCULAR ZINC(II) COMPLEX BASED ON 2,6-BIS{[(4-ISOPROPYLPHENYL) IMINO]ETHYL}PYRIDINE

Abstract

A new monocular zinc(II) complex [Zn(L1)Cl2] (complex 1), where L1 stands for 2,6-bis{[(4-isopropylphenyl)imino]ethyl}pyridine is synthesized and characterized. Complex 1 crystallizes in the monoclinic crystal system in the P21/n space group with a = 10.941 Å, b = 15.918 Å, c = 16.199 Å, β = 107.60°, and Z = 4. L1 acts as a tridentate ligand and is coordinated to the Zn1 atom in a five-coordinated trigonal bipyramidal geometry. The thermogravimetric analysis suggests that complex 1 can be stable up to 351 °C. The study of the photoluminescent properties indicates that complex 1 shows intense metal-perturbed π–π* intraligand fluorescence in the solid state.
