<p>The crystal structure of tetracoordinated a zinc(II) complex with two 2-(1,4,5,6-tetrahydropyrimidin-2-yl)phenolate ligands was determined by X-ray crystallography. The title compound was synthesized by a reaction of ZnCl2 and 2-(1,4,5,6-tetrahydropyrimidin-2-yl)phenolate in ethanol. The compound crystallizes in the monoclinic space group C2/c and Z = 4 with cell parameters a = 13.7667(14)Å, b = 11.4666(11)Å, c = 12.2213(12)Å, β = 116.242(2)°, V = 1730.4(3)Å3. The R1 [I > 2σ(I)] and wR2 (all data) values are 0.0401 and 0.1064, respectively, for all 2104 independent reflections. The crystal structure was solved as a two-component twin. The title compound was found to take a pseudo-tetrahedral geometry with the bis-bidentate coordination mode. The non-coordinating N–H bond in the ligands formed intermolecular hydrogen-bonds to construct one-dimensional chain structures.</p>
