Abstract Reaction of dmpe (bis(1,2-dimethylphosphino)ethane) with CrCl3(THF)3 gives deep red crystalline Cr2(dmpe)3(Cl)6·2CH2Cl2 in 85% yield. The X-ray crystal structure of the title compound shows a bridgingtrans dmpe ligand between two isolated Cr(III) centers. Each Cr(III) atom bears a chelating dmpe group and three Cl atoms in a roughly octahedral geometry. Crystal data: C20H48Cl10Cr2P6,M=933.0, monoclinic,P21/n,a=9.221(3),b=10.587(2),c=21.868(2) Å,β=98.962(3)°,D calc=1.47 g cm−3,Z=2. FinalR=0.054,R w =0.063 from 1964 observed reflections (I〉3σ(I)), 3489 measured.
