摘 要: | The self-assembly reactions of [MOS3]^2- (M = W, Mo) with CuS2COCH3 in DMF produced two novel dodecanuclear Mo(W)/Cu/S heterometallic clusters, [Et4N]4[{MOS3}3Cu6S2- (CuS2COCH3)3]·H2O (1: M = W; 2: M = Mo). Cluster 1 crystallizes in hexagonal, space group P-62c with a = 16.5612(3), b = 16.5612(3), c = 16.4660(5)A, Z = 2, V = 3911.13(16)A^3, Dc = 1.935 g/cm^3, μ(MoKα) = 7.269 mm^-1, F(000) = 2192, the final R = 0.0289 and wR = 0.0789 for 2425 observed reflections (I 〉 2σ(I)). Cluster 2 is isomorphous to 1 with similar crystal parameters. X-ray analysis reveals that both clusters consist of three incomplete cubane-like cluster units {MOS3Cu3S2COCH3}, which are linked together by two μ3-S atoms.

Abstract: | The self-assembly reactions of [MOS_3]~(2-) (M = W, Mo) with CuS_2COCH_3 in DMF produced two novel dodecanuclear Mo(W)/Cu/S heterometallic clusters, [Et_4N] _4[{MOS_3}_3Cu_6S_2-(CuS_2COCH_3) _3]·H_2O (1: M = W; 2: M = Mo). Cluster 1 crystallizes in hexagonal, space group P-62c with α= 16.5612(3), b = 16.5612(3), c = 16.4660(5) A, Z = 2, V= 3911.13(16) A~3, D_c = 1.935 g/cm~3,μ(MoKa) = 7.269 mm~(-1), F(000)=2192, the final R = 0.0289 and wR = 0.0789 for 2425 observed reflections (I> 2σ(I)). Cluster 2 is isomorphous to 1 with similar crystal parameters. X-ray analysis reveals that both clusters consist of three incomplete cubane-like cluster units {MOS_3Cu_3S_2COCH_3}, which are linked together by two μ_3-S atoms. |
