Abstract
The crystal structure of the title compound, [WBr(NO)(C6H16P2)2], reveals a distorted octahedral 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(dimethylphosphino)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.

Summary
The crystal structure of the title compound, [WBr(NO)(C6H16P2)2], reveals a distorted octahedral geometry around the W centre. The W atom lies on a special position at an inversion centre (the Br and NO ligands are disordered). The bis(dimethylphosphino)ethane ligand is severely disordered (site occupancy factors 0.52 and 0.48). This is the first structure of a tungsten species with nitrosyl and bromide ligands.
