Structural studies in main-group chemistry. Part XIII. The structure of bis(N-benzoyl-N-phenylhydroxylaminato)dichlorotin(IV)

Abstract

The structure of the title compound has been determined by single-crystal X-ray diffractometry using Patterson and Fourier techniques. Crystals are orthorhombic, space group P2₁2₁2₁, with Z= 12 in a unit cell of dimensions a= 24.336(4), b= 33.192(4), and c= 9.408(2)Å. The structure has been solved by constructing a pseudo-cell related to the unit cell such that a′=a, b′=b//₃, and c′=c, and re-indexing the reflections such thaf h′=h, k′=k//₃ and I′=I, and refined by block-diagonal least-squares methods to R 0.081 for 1 942 re-indexed reflections. The tin atom is co-ordinated in a distorted octahedral fashion by two chlorine atoms occupying cis positions [Sn–Cl 2.361(5)Å, Cl–Sn–Cl 99.0(2)°] and by two N-benzoyl-N-phenylhydroxylaminato-residues which chelate the tin nearly symmetrically [Sn–O 2.04(2), 2.1 l(2)Å].
