Abstract
The crystal and molecular structure of the title compound has been determined by the heavy-atom method and refined by least-squares techniques on 1 639 independent X-ray diffractometer data to R 0.059. Crystals are orthorhombic, space group Pbca, with a= 29.76(4), b= 9.80(1), c= 19.95(3)Å, and Z= 8. The structure consists of discrete monomeric units containing seven-co-ordinate tin in a pentagonal-bipyramidal geometry, the two nitrate groups and the triphenylphosphine oxide molecule being equatorial, with the two phenyl rings at the apices. One of the two rings is disordered between two crystal orientations.Keywords
