A new zinc (Ⅱ ) complex with 3,4, 5-trimethoxybenzoic acid and 2-methylimidazole [Zn(tmba)2 ( meim)2] (tmba = ( OCH3 )3C6H4COO-, meim = 2-methylimidazole) has been synthesized and characterized by elemental analyses and spectroscopic techniques (FT-IR and fluorescence). The molecular structure of the complex has been determined by the single crystal X-ray diffraction. The complex crystallizes in the orthorhombic system with space group Pca21 , where the four coordinated Zn atoms are surrounded by two nitrogen atoms of two meim ligands and two oxygen atoms of two tmba ligands in a tetrahedron geometry. Besides electrostatic interaction, hydrogen bonding network formed by N-H…O stabilizes crystal lattice in the complex.
