摘要
The reaction of[（η^5-C5Me5）2Mo2（μ3-S）（μ-S）3（CuCl）]1 with Na2S in MeCN produced a trinuclear cluster [（η^5-C5Me5）2Mo2（μ3-S）（μ-S）3（CuCl）] 2. 2 crystallizes in the monoclinic system, space group P21/c with a = 15.563（3）, b = 8.9547（18）, c = 17.846（4） A, β = 101.29（3）°, V = 2438.9（9） A^3, Z = 4, Dc = 1.878 g/cm^3, T = 193（2） K, C20H30ClCuMo2S4, Mr = 689.60, F（000） = 1376, μ（MoKa） = 2.335 mm ^-1, S = 1.050, R = 0.0305 and wR = 0.0688 for 4033 observed reflections with I 〉 20-（I）. In the structure of 2, one [（η^5-C5Me5）2Mo2（μ-S）2S] moiety and one CuCI unit are assembled into an incomplete cubane-like [Mo2S4Cu] core framework, in which the Cu center adopts a distorted tetrahedral geometry coordinated by one ,μ3-S atom, two μ-S atoms and one terminal chloride. The two Mo…Cu contacts are 2.7519（7） and 2.7689（8） A, respectively.
