Crystal structure of cis-di-chlorido-(1,4,8,11-tetra-aza-cyclo-tetra-decane-κ⁴N)chromium(III) (oxalato-κ²O¹,O²)(1,4,8,11-tetra-aza-cyclo-tetra-decane-κ⁴N)chromium(III) bis(perchlorate) from synchrotron data.

ABSTRACT: In the asymmetric unit of the title compound, [CrCl₂(C₁₀H₂₄N₄)][Cr(C₂O₄)(C₁₀H₂₄N₄)](ClO₄)₂ (C₁₀H₂₄N₄ = 1,4,8,11-tetra-aza-cyclo-tetra-decane, cyclam; C₂O₄ = oxalate, ox), there are two independent halves of the [CrCl₂(cyclam)]⁺ and [Cr(ox)(cyclam)]⁺ cations, and one perchlorate anion. In the complex cations, which are completed by application of twofold rotation symmetry, the Cr^III ions are coordinated by the four N atoms of a cyclam ligand, and by two chloride ions or one oxalate bidentate ligand in a cis arrangement, displaying an overall distorted octa-hedral coor
