  Chelating and ligand-transfer studies of the complexes cis-[Mn(CO)4(SeR)2]−: crystal structures of heterotrinuclear [(CO)4Mn(μ-SeMe)2Ni(μ-SeMe)2Mn(CO)4] with a distorted square planar NiII–selenolate core and [PPN]2[Cl2Pd(μ-SePh)2PdCl2]

  摘要：

  Trinuclear selenolate complexes [(CO)(4)Mn(mu-SeR)(2)Ni(mu-SeR)(2)Mn(CO)(4)] (R = Me, Ph) containing a distorted square planar Ni(Se)(4) core have been synthesized by the reaction of Ni(NO3)(2). 6H(2)O/NiCl2 with the chelating metalloligand cis-[PPN][Mn(CO)(4)(SeR)(2)] in MeCN. Their structures were elucidated on the basis of IR, UV-Vis, CV, and NMR spectra. X-ray crystallography confirmed the heterotrinuclear structure in the solid state with a Ni-II-Se distance of 2.331(1) Angstrom, and a Ni-II... Mn-I distance of 3.428(2) Angstrom (average). The dependence of geometry on electron population and the larger Ni-II... Mn-I distances are adopted to rationalize the construction of the complex [(CO)(4)Mn(mu-SeMe)(2)Ni(mu-SeMe)(2)Mn(CO)(4)] with a distorted square planar Ni-II(Se)(4) core. Further reaction of cis-[PPN][Mn(CO)(4)(SePh)(2)] with PdCl2 afforded [PPN](2)[Cl2Pd(mu-SePh)(2)PdCl2]. Its structure has been determined. This investigation shows that cis-[Mn(CO)(4)(SeR)(2)](-) serves as a chelating metalloligand and selenolate ligand-transfer reagent. (C) 1999 Elsevier Science S.A. All rights reserved.
