| 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. |
