Re（V）起始原料[ReO（PPh 3）（2）Cl-3]与XN（Y）Z [X = Y = 2-吡啶基甲基，Z = -CH 2CO 2 Et（（LEt）-Et-1），-CH 2CH 2CO 2 Et（（LEt）-Et-2），-CH 2CH 2CH 2CH 2CH（NHCO_2But）CO_2H（（LH）-H_3）; X = 2-吡啶甲基，Y = 2-（1-甲基咪唑基）甲基，Z = -CH_2CO_2Et（L_4Et）]，得到了[ReCl_3（（LR）-R-n）]型铼（Ⅲ）双金属配合物。配合物是单核的，顺磁性的物种与氯化物配体的面部几何形状。三齿（LR）-R-n配体的氮给体使配合物的畸变八面体配位球完整。晶体数据：[ReCl 3（（LEt）-Et-1）]（1），单斜晶系，C2/m，a = 16.088（3）Angstrom，B = 9.980（2）Angstrom，c = 12.829（2）Angstrom，β = 91.384（3），Z= 4，D-calc，= 1.967 g/cm（-3）;[ReCl 3（（LEt）-Et-4）]（4），单斜晶系，C2/c，a = 22.880（1）埃，B = 7.4926（4）埃，c = 22.560（1）埃，β = 94.186（1）度，Z = 8，D-calc = 2.001 g/cm（-3）。
The reactions of the Re(V) starting material [ReO(PPh3)(2)Cl-3] with ligands of the type XN(Y)Z [X = Y = 2-pyridylmethyl, Z = -CH2CO2Et ((LEt)-Et-1), -CH2CH2CO2Et ((LEt)-Et-2), -CH2CH2CH2CH2CH(NHCO2But)CO2H ((LH)-H-3); X = 2-pyridylmethyl, Y = 2-(1-methylimidazolyl)methyl, Z = -CH2CO2Et (L4Et)] yielded the Re(III) trichloride complexes of the type [ReCl3((LR)-R-n)]. The complexes are mononuclear, paramagnetic species with a facial geometry of the chloride ligands. The nitrogen donors of the tridentate (LR)-R-n ligands complete the distorted octahedral coordination spheres of the complexes. Crystal data: [ReCl3((LEt)-Et-1)] (1), monoclinic, C2/m, a = 16.088(3) Angstrom, b = 9.980(2) Angstrom, c = 12.829(2) Angstrom, beta = 91.384(3), Z= 4, D-calc, = 1.967 g/cm(-3); [ReCl3((LEt)-Et-4)] (4), monoclinic, C2/c, a = 22.880(1) Angstrom, b = 7.4926(4) A, c = 22.560(1) Angstrom, beta = 94.186(1)degrees, Z = 8, D-calc = 2.001 g/cm(-3).
