Synthesis and crystal structure of the complex of triadimefon and zinc chloride

The new compound was synthesized by the reaction of ZnCl2 and triadimefon (ratio 1: 2) in ethanol solution refluxing for 6 hours. The crystal used for X-ray analysis was obtained by slow evaporation of the solution at room temperature. It crystallizes in the monoclinic system, space group P2/ n. The lattice parameters are: a = 1.58916(6) nm, b = 0.60634(2) nm, c = 1.83566(8) nm, beta = 93.979(2)degrees, V = 1.7645(1) nm(3), Z = 2, D-c = 1. 362g . cm(-3), F(000) = 744. 00, mu(Mo Kalpha) = 1. 038mm(-1), R-1 = 0. 042, omegaR(2) = 0. 106. In the complex, the Zn (II) cation is tetrahedrally coordinated to two triadimefon ligands and two chloride in cis disposition. The title complex was also characterized by elemental analysis, molar conductance, IR and TG-DTA.
