Synthesis and structure of [M(CO)4{(PPh2)2CHAu(PPh3)}] (M = Cr, Mo, W)
The reaction of diethyl ether solutions of Li[M(CO)4{(PPh2)2CH}] with [AuCl(PPh3)] gives [M(CO)4{(PPh2)2CHAu(PPh3)}] (M = Cr, Mo, W). The structure of the derivative with M = Mo was determined by single-crystal X-ray diffraction at 173 K. Crystals are monoclinic, space group P22, a = 13.552(3), b =...

| Sumario: | The reaction of diethyl ether solutions of Li[M(CO)4{(PPh2)2CH}] with [AuCl(PPh3)] gives [M(CO)4{(PPh2)2CHAu(PPh3)}] (M = Cr, Mo, W). The structure of the derivative with M = Mo was determined by single-crystal X-ray diffraction at 173 K. Crystals are monoclinic, space group P22, a = 13.552(3), b = 17.390(4), c = 17.390(4) A ̊, β = 90.94(2)°, Z = 4 and R(F) = 0.031. The two independent molecules are very similar. The molybdenum and the gold atoms display octahedral and linear geometries, respectively; the shortest intramolecular molybdenum-gold interaction is 4.52 Å. © 1995. |
