Abstract
In the title compound, [CrCl2(C3H10N2)2]2[ZnCl4], the CrIII atom is coordinated by four N atoms of propane-1,3-diamine (tn) and two Cl atoms in a trans arrangement, displaying a distorted octahedral geometry with crystallographic inversion symmetry; the Zn atom in the [ZnCl4]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 intermolecular hydrogen bonds involving the tn NH2 groups as donors and chloride ligands of the anion and cation as acceptors are observed.
