title: [CrBr2(NH3)4][CrBr4(NH3)2], a new chromium(III) complex.
abstract: Green single crystals of trans-tetraamminedibromidochromium(III) trans-diamminetetrabromidochromate(III), [CrBr2(NH3)4][CrBr4(NH3)2], are found to contain two symmetry-independent sixfold coordinated Cr(III) cations on centres of inversion. The structure is composed of octahedral trans-[CrBr2(NH3)4]+ cations and octahedral trans-[CrBr4(NH3)2]- anions, and adopts a distorted CsCl-type lattice. The cations and anions are linked by N-H...Br interactions. This is the first example in which both ions are mixed ammine-bromide Cr(III) complexes.
