Abstract

Crystals of [Rh(NCMe)3(NO)(PPh3)2][PF6] 2 are monoclinic, space group P21/n, with a = 14.053(8), b = 27.512(15), c = 11.914(8) Å, β = 97.29(5)°, and Z = 4. The structure has been elucidated by the analysis of 8 502 observed intensities recorded at ca. 215 K on a four-circle diffractometer, and refined by least squares to R 0.075. In the cation the metal is octahedrally bound to trans-phosphorus atoms (mean Rh-P 2.405 Å) and three acetonitrile ligands [Rh-N 2.030(7). 2.104(7), and 2.308(8) Å] the last lying trans to the nitrosyl function [Rh-NO 2.026(8) Å] which acts as the one-electron donor [NO]- [Rh-N-O 118.4(6)°]. The two hexafluorophosphate counter ions exhibit differing thermal activity which is correlated to their crystal environments.
