Structure of the Chromium(III) salt [Cp-2*Cr](+)[Cp*CrCl3](-)

Journal article

© 1998 International Union of Crystallography The title compound, bis(η5-pentamethylcyclopentadienyl) chromium (III) trichloro (η5-pentamethylcyclopentadienyl)chromium(III), [Cr(C10H15)2][CrCl3(C 10-H15)], is a salt consisting of discrete anionic [{η5-C5(CH3)5}CrCl 3]- and cationic [{η5-C5(CH3)5} 2Cr]+ chromium(III) species. The anion adopts a 'three-legged piano-stool' structure, whereas the cation displays a staggered orientation of the C5 rings and approximates to D5d local symmetry. The Cr - C distances range from 2.177 (5) to 2.208 (4) Å in the cation and from 2.234 (4) to 2.265 (5) Å in the anion; Cr - Cl distances in the anion fall in the range 2.320 (1)-2.331 (1)Å.
