Abstract
Two novel cadmium complexes with TMB (HTMB = 3,4,5-trimethoxybenzoic acid) are synthesized by the solution evaporation method. The structure and luminescent property of the two complexes are characterized by single crystal and powder X-ray diffraction, FT-IR spectroscopy, and photoluminescence emission spectra. Cd2(TMB)4(H2O)4·H2O (1) is a binuclear complex containing two Cd ions at a distance of 4.091 Å, both coordinated in octahedral geometry. Along the [100] direction, a 1D chain linked by intermolecular hydrogen bonds is formed. Cd(TMB)2(IM) (H2O)2 (2) is a mononuclear complex in which the Cd ion coordination can be described as a distorted pentagonal bipyramid, and weak hydrogen bonding interactions are present in its molecule. The fluorescent measurement shows that both complexes exhibit strong emission in the solid state at room temperature. Powder X-ray diffraction confirmed their crystallinity and purity.
