摘要

The rhodium diacetate complexes with dioxane Rh-2(OAc)(4)(Diox)(2) (I) and dimethyl sulfoxide Rh-2(OAc)(4)(Dmso)(2) (II) have been synthesized by dissolving rhodium diacetate [Rh-2(OAc)(4)] in dioxane (Diox) and dimethyl sulfoxide (Dmso) with the further slow evaporation of the solvent. Rh-2(OAc)(4)[(4-FC6H4)(3)Sb](2) (III) has been synthesized by the reaction between [Rh-2(OAc)(4)] and tris-4-fluorophenylantimony in acetonitrile. Using X-ray diffraction, it has been established that the rhodium atoms in complexes I-III have a slightly distorted octahedral coordination: the angles ORhRh, ORhO, 176.56(6)degrees-177.72(4)degrees (I); SRhRh, ORhO, 174.79(9)degrees-179.271(13)degrees (II); SbRhRh, ORhO 173.590(19)degrees-175.48(10)degrees (III); bonds Rh-Rh, Rh-O-Ac, Rh-O-Diox, 2.380(3), 2.037(3)-2.046(3), 2.335(3) angstrom (I); Rh-Rh, Rh-O, Rh-S, 2.4288(10), 2.034(3)-2.046(3), 2.7258(10) angstrom (II); Rh-Rh, Rh-O, Rh-Sb, 2.4183(12), 2.033(3)-2.044(3), 2.7113(13)-2.7120(13) angstrom (III). The structural organization in crystals of complexes I-III is caused by weak hydrogen bonds H center dot center dot center dot O-Diox (2.50-2.72 angstrom), H center dot center dot center dot O-Ac (2.57 angstrom) (I), H center dot center dot center dot O-Dmso 2.48-2.71 angstrom, H center dot center dot center dot O-Ac 2.65, 2.66 angstrom (II) H center dot center dot center dot F (2.56-2.62 angstrom), and H center dot center dot center dot O (2.68-2.71 angstrom) (III).
