Abstract

A new polymorph of HRh(CO)(PPh3)3, with a υRh-H of 2013 cm−1, has been isolated by crystallization fromtert-butyl methyl ether/tetrahydrofuran. The crystals are monoclinic (space groupP21/n), witha=21.48(2) Å,b=14.92(2)Å,c=14.52(1)Å,β=107.95(8)°. A finalR value of 0.065 was obtained using 2243 reflections which hadInet>2.5σ(Inet). The structure of the new polymorph has a similar coordination geometry to the known polymorph, but a different conformation of one of the phenyl rings.
