title: Pentacarbonyl[tris[4-(methylsulfonyl)phenyl]stannyl]manganese(I): an unexpected tetragonal structure.
abstract: The title compound, [MnSn(C(7)H(7)O(2)S)(3)(CO)(5)], is asymmetric but crystallizes in the highly symmetric tetragonal space group I-4. This is achieved without the need for any disorder, either around the Sn atom or in any of the methylsulfonyl groups. The environment around the Sn atom has the following geometry: Sn-Mn = 2.6564 (7) A, mean Sn-C = 2.175 (5) A, mean C-Sn-C = 103 (2) degrees and mean C-Sn-Mn = 115 (6) degrees. The crystal packing is assisted by weak Sn.O interactions between adjacent columns of molecules, with the resulting geometry at Sn approaching highly distorted trigonal-bipyramidal.
