Bis[μ-bis(diphenylphosphino)hexane-P:P']digold(I) Hexafluoroantimonate Acetonitrile Solvate

In the title compound, [Au2(C6H12{P(C6H5)2}2)2][SbF6]2. 1.6CH3CN, the [{Ph2P-(CH2)6-PPh2}2Au2]2+ cation lies with its Au atoms on a twofold axis and the [SbF6]− anions in general positions. Main bond lengths and angles include Au-P 2.307 (2) and 2.311 (2) A, P-Au-P 172.7 (1) and 174.2 (1)°. There are no significant intramolecular or intermolecular Au⋯Au interactions. The C-atom chain of the hexamethylene moiety is maximally extended with C-C-C-C torsion angles in the range −170.4 (7) – −177.7 (7)° and all the Au-P-C-C and P-C-C-C conformations are gauche.
