Et4N[NO3(SnClPh3)2(SnPh3NO3)]: a trinuclear organostannate complex and related derivatives

Abstract

Four new di- and triorganonitrato stannate complexes and related derivatives have been synthesized and characterized by infrared and Mössbauer spectroscopy. The structure of Et4N[NO3(SnClPh3)2(SnPh3NO3)] (1) has been determined by single-crystal X-ray diffraction analysis. In the trinuclear organostannate complex, each SnIV atom is five-coordinated and adopts a trigonal-bipyramidal trans-OXSnC3 (X=O or Cl) geometry. The overall coordination environment of the SnIV atoms is trans-octahedral for 2 and 3 or cis-trigonal-bipyramidal for 4. In the related derivatives, the NO3- anions behave as monodentate ligands.
