Crystal structure of bis-[trans-di-chlorido-bis(propane-1,3-di-amine-κ²N,N')chromium(III)] dichromate from synchrotron data.

ABSTRACT: The structure of the title compound, [CrCl₂(tn)₂]₂[Cr₂O₇] (tn = propane-1,3-di-amine; C₃H₁₀N₂), has been determined from synchrotron data. The asymmetric unit contains one Cr^III complex cation and half a [Cr₂O₇]^2- anion. In the complex cation, the Cr^III ion is coordinated by the four N atoms of two propane-1,3-di-amine (tn) ligands in the equatorial plane and by two Cl atoms in a trans configuration, displaying a distorted octa-hedral coordination sphere. The two six-membered rings in the complex cation have an anti chair-chair conformation with respect to each other. The mean Cr-N(tn) and Cr-Cl bond lengths are 2.09 (1) and 2.320 (2)
