Bis(N-benzyl-N-isopropyl-dithio-carbamato-κS)di-n-butyl-tin(IV)

Abstract

The Sn atom in the title compound, [Sn(C4H9)2(C11H14NS2)2], exists in a tetra-hedral C2S2Sn coordination geometry. The geometry is distorted towards skew-trapezoidal-bipyramidal owing to the proximity of the double-bonded S atoms. The C2Sn angles range from 129.0 (2) to 136.9 (2)°, the covalent Sn - S lengths from 2.529 (1) to 2.544 (1) Å, and the dative Sn←S lengths from 2.831 (1) to 3.042 (1) Å in the five independent mol-ecules comprising the asymmetric unit. Two of the butyl groups were modelled over two positions of equal occupancy. All butyl groups were refined with distance restraints.
