(p-Nitrobenzoato)triphenyltin at 298 K

R. A. Howie, J. L. Wardell, S. M. S. V. Wardell and P. J. Cox

Synopsis: The structure of the title compound at 298 K is virtually identical to the 173 K structure reported previously [Weng, Das & Robinson (1990). Malays. J. Sci. 12, 57]. The primary coordination of the Sn atom in both molecules of the asymmetric unit is in the form of a distorted tetrahedron. The distortion towards a trigonal-bipyramidal arrangement is brought about by a weak interaction between the Sn atom and the carbonyl O atom of the benzoate moiety.
