The crystal structure indicated the tungsten atom to be seven-coordinate with the geometry most closely approximated by a capped trigonal prismatic environment, the capping group being a bromine atom (W—Br, 2.686(5) Å).
La face cappée comprend l'atome de brome résiduel (W—Br, 2,695(5) Å), un atome de phosphore (W—P, 2,465(9) Å) et les deux atomes d'arsenic du ligand bidentate (W—As, 2,619(3) et 2,526(4) Å).
