Abstract

The crystal structure of the title compound, [WBr(NO)(C(6)H(16)P(2))(2)], reveals a distorted octa-hedral geometry around the W centre. The W atom lies on a special position at an inversion centre (the Br and NO ligands are equally disordered). The bis-(dimethyl-phosphino)ethane ligand is also severely disordered (site occupancy factors 0.52 and 0.48). This is the first structure of a tungsten species with nitrosyl and bromide ligands.
