摘要

In the centrosymmetric tetra-nuclear title compound, Sn4(C4H9)8(C7H5O3) 4O2, one of the two independent Sn atoms is five-coordinate in a cis-C2SnO3 trigonal-bipyramidal geometry C - Sn - C = 142.7 (1)°; the geometry is distorted owing to a long Sn�O(double bond) inter-action Sn�O = 2.862 (1) �. The other Sn atom has a bent R 2Sn skeleton C - Sn - C = 144.0 (1)°, but the geometry is best regarded as being a trans-C2SnO4 octa-hedron as the Sn-O(single bond) inter-action is shorter Sn - O = 2.674 (1) �.
