  Rhodium complexes with diimines derived from glyoxal: crystal structure of [Rh(SnCl3)(NBD)(GCH)] (NBD = norbornadiene; GCH = gloxal bis(cyclohexylimine)

  摘要：

  [{Rh(L(2))Cl}(2)] (L(2) drop COD, or norbornadiene (NBD)) react with alpha-diimines (LL) derived from glyoxal, irrespective of the stoichiometric ratios employed, to give [Rh-2(L(2))Cl-2(LL)] when L(2) drop COD or [Rh(Cl)(L(2))(LL)] when L(2) = NBD. Solutions of COD compounds contain dinuclear [{Rh(COD)(Cl)}(2)(mu-LL)] species with bridging LL groups and ionic [Rh(COD)(LL)](+)[Rh-(COD)Cl-2](-) species, in temperature-dependent ratios. The NBD compounds are pentacoordinated in the solid state and undergo rearrangements in solution. When the reactions are performed in the presence of SnCl2, pentacoordinated [Rh(SnCl3)-(diolefin)(LL)] are obtained, which in solution undergo SnCl3- dissociation. The molecular structure of [Rh(SnCl3)(NBD)(GCH)] (GCH = glyoxalbis(cyclohexylimine)) has been determined by an X-ray diffraction study. It is best described as distorted square pyramidal with the equatorial positions occupied by the diolefin and the diimine respectively, and the SnCl3 fragment in the apical position.
