Structure of bis[α-(1,2,4-triazole-1-yl)-acetophenone]dichorozinc(II) complex [ZnCl2(C2H2N3CH2COPh)2]

The crystal and molecular structure of [ZnCl2(N-4-trzCH(2)COPh)(2)] (trz = 1,2,4-triazole) has been determined by X-ray crystallography. It crystallizes in the monoclinic system, space group C2/c, with lattice parameters a = 26.7892(4) Angstrom, b = 4.9392(2) Angstrom, c = 20.7872(1) Angstrom, = 127.517 (1)degrees, and Z = 4. The complex has C-2 symmetry. The coordination geometry of each Zn atom is distorted tetrahedral formed by two Cl atoms and two tertiary N atoms of the alpha-(1,2,4-triazole-1-yl)-acetophenone ligands. The two equivalent Zn-Cl and Zn-N bonds form bond angles around the Zn(II) atom in the range 101.4(1)-120.8(1)degrees. C-H...O intermolecular interactions link the molecules in infinite chains in the [101] direction.
