biostudies-literatureUnknown68(Pt 5)Pei ATThe title compound, [ZnCl(2)(C(13)H(20)N(2)O(2))], was first reported in the monoclinic space group P2(1)/n [Han et al. (2010 ▶). Acta Cryst. E66, m469]. This investigation reveals a triclinic polymorph in the space group P-1 with an asymmetric unit that contains two independent mol-ecules of the mononuclear zinc(II) complex. In each mol-ecule, the Zn(II) atoms are coordinated in a bidentate fashion by the phenolate O and imine N atoms of the Schiff base ligand. Two Cl(-) anions complete the tetra-hedral coordination in each case. The most obvious difference between the two forms is that the Zn-L (L = O, N, Cl) bond lengths in both unique mol-ecules are longer than those found in the monoclinic polymorph, or indeed in other similar complexes. In the crystal, mol-ecules are linked through N-H⋯O and N-H⋯Cl hydrogen bonds, forming chains along the b axis.Acta crystallographica.
