New complex of Zn(II) with 3,4,5-trimethoxybenzoate and 2-methylimidazolyl: Synthesis, structure, and luminescence properties

Abstract

A new zinc(II) complex Zn(TMB)2(2-MIM)(H2O)2 (I), where HTMB is 3,4,5-trimethoxybenzoic acid, 2-MIM is 2-methylimidazole, was synthesized and characterized by Powder X-ray diffraction, FT-IR and photoluminescence spectrum. The complex crystallizes in the monoclinic crystal system (space group C2/c) with the unit cell parameters: a = 18.104(9), b = 8.509(4), c = 17.688(9) A, β = 103.185(9)°, Z = 4, R1 = 0.0740 and wR2 = 0.1790. At room temperature the photoluminescence spectrum of complex I in the solid state exhibits maximum excitation at 314 nm and maximum emission at 337 nm.
