Preparation and Crystal Structure of [(O)MoCu_3(μ_3-S)_3(μ_3-Cl)(PPh_3)_3]·2THF |
| |
| Abstract: | The title compound (O)MoCu3(μ3-S)3(μ3-Cl)(PPh3)3]·2THF was prepared by the reaction of (NH4)6Mo7O24·4H2O with (PPh3)2CuCl2 and NH4HS in NH3· H2O to get orange-red crystal, followed by treatment with THF, and its crystal structure was determined by X-ray diffraction. The title compound crystallizes in the monoclinic, space group P21/c, Z = 4, a= 11. 742(2), 6 = 28.186(7), c=19. 304(3)(?) , β=100. 57(2)°, V=6280. 4(?)3. Dc= 1. 46g/cm3, R = 0. 063, Rw =0. 052. The title compound molecule has a cluster core {MoCu3 (μ3-S)3(μ3-Cl)}. The average distance of Cu-Mo is 2. 716(?). |
