Electrophilic attack of group 11 and 12 metal fragments on the dinuclear anions [M2(μ-σ:C2Ph)(CO)4(η-C 5H5)2]- (M = Mo, W). Crystal structure of the transversally bridged alkyne complex [W2(μ-PhC2AuPPh3)(CO) 4(η-C5H5)2]

The dinuclear anions [M2(μ-σ:C2Ph)(CO)4(η-C 5H5)2]- (M = Mo, W) react with gold halides ClAuPR3 (R = Ph, Me) in tetrahydrofuran to yield the μ-alkyne bonded complexes [M2(μ-PhC2AuPR3)(CO) 4(η-C5H5)2] [M = Mo, R = Ph (1a), R = Me (2a); M = W, R = Ph (1b), R = Me (2b)] in good yield. The structure of 1b has been determined by X-ray diffraction methods. The crystals are monoclinic, space group P21/c with Z = 4 in a unit cell of dimensions a = 8.417(4) A?, b = 16.386(6) A?, c = 25.352(9) A?, β = 90.55(2)°. The structure has been solved from diffractometer data by direct and Fourier methods and refined by full-matrix least-squares on the basis of 3865 observed reflections to R and Rw values of 0.0314 and 0.0362, respectively. The complex displays a W2C2 tetrahedral core with W-W and the C-C bond distances of 2.958(1) and 1.387(15) A?, respectively. The reaction between the dinuclear anions and HgCl2 leads to a new class of pentametallic symmetric mercury derivatives where the mercury atom forms two Hg-C(μ-alkyne) bonds bridging two cluster units.
