摘 要:报道一个手性化合物R-cis-Rh_2(Ph_2C_6H_4)_2(Protos)_2(CH_3CN)_(2·3)CH_3CN(Hprotos=N-(4-methylphenylsulfonyl-(L)-proline)(1)的晶体结构,该晶体结构是从R-cis-Rh_2(Ph_2C_6H_4)_2(Protos)_2(H_2O)_2(R-2)与CH_2Cl_2及CH_3CN的混合溶液中。重结晶得到的.该晶体属于正交晶系,空间群P2_12_12_1,晶胞参数为a=9.8148(16),b=12.111(2),c=57.199(10),V=6799。(2)~3,Z=4,分子式为C_(70)H_(71)N_7O_8P_2Rh_2S_2,分子量Mr=1470.22,Dc=1.436g/cm^3, F(000)=3024和μ(MoKα)=6.54 mm-1.对9872个可观测衍射点最终偏差因子(对I> 2σ(I)的衍射点)R=0.0863,wR=0.2013;对全部衍射点(绝对结构参数=0.08(6))最终偏差因子R=0.0903,wR=0.2033.该晶体结构是一个不同的桥接配位体与双金属形成的桨轮状复合物,包含一个Rh (II)双核心及与其桥接呈顺式构型的两个邻位金属化的膦基和两个N-(4-methylphenylsulfonyl-(L)-proline,。在每个轴向位置分别有一个CH_3CN分子.Rh-Rh键长为2.524(1) .The crystals of enantiopure R-cis-Rh2(Ph2C6H4)2(Protos)2(CH3CN)2·3CH3CN (Hprotos=N-(4-methylphenylsulfbnyl- (L)-proline) (1) were obtained from the recrystallization of R-cis-Rh2(Ph2C6H4)2(Protos)2(H2O)2(R-2) in CH2Cl2/CH3CN. Compound 1 crystallizes in orthorhombie, space group P212121 with a = 9.8148(16), b = 12.111(2), c = 57.199(10) A^°, V= 6799 (2)A^°3, Z = 4, C70H71N7O8P2Rh2S2, Mr = 1470.22, De = 1.436 g/cm^3, F (000) = 3024 and μ(MoKα) = 6.54 mm^-1.The final R = 0.0863 and wR = 0.2013 tor 9872 observed reflections with I 〉 2σ (I) and R = 0.0903 and wR = 0.2033 tor all data with absolute structure parameter = 0.08(6).Compound 1 is a paddlewheel dimetal complex with mixed bridging ligands.h contains a dinuelear Rh (Ⅱ) core bridged by two orthometalated phosphines and two L-type protos groups in a eisoid arrangement, with a molecule of CH3CN in each axial position.The Rh-Rh distance is 2.524(1)A^°.
