Abstract:
In the title compound, [CrCl(2)(C(3)H(10)N(2))(2)](2)[ZnCl(4)], the Cr(III) atom is coordinated by four N atoms of propane-1,3-diamine (tn) and two Cl atoms in a trans arrangement, displaying a distorted octa-hedral geometry with crystallographic inversion symmetry; the Zn atom in the [ZnCl(4)](2-) anion lies on a -4 axis. The orientations of the two six-membered chelate rings in the complex cation are in an anti chair-chair conformation with respect to each other. The Cr-N bond lengths are 2.087 (6) and 2.097 (6) Å. The Cr-Cl and Zn-Cl bond lengths are 2.3151 (16) and 2.3255 (13) Å, respectively. Weak inter-molecular hydrogen bonds involving the tn NH(2) groups as donors and chloride ligands of the anion and cation as acceptors are observed.
