Me3SnN(SO2Me)2 . 4,4'-bpy is obtained as an amorphous powder by treating a suspension of Me3SnN(SO2Me)2 in Et2O with one equivalent of 4,4'-bipyridine. It crystallizes from MeCN as a labile (1/1)-solvate. The crystallographic data of the latter at -95-degrees-C are: monoclinic, space group P2(1)/n, a 930.9(2), b 1105.9(4), c 2227.4(7) pm, beta 92.27(2)-degrees, U 2.2910 nm3, Z = 4. The crystal packing consists of linear-polymeric [Me3Sn(mu-4,4'-bpy)-]nn+ cations in which the monomers are related by a glide plane, discrete (MeSO2)2N- anions, and non-coordinating MeCN molecules. The angle between the C5N planes of the bipyridine is 32-degrees. The tin atom has a trigonal-bipyramidal environment with two apical nitrogen atoms: Sn-N 241.1/242.0, Sn-C 211.9-213.0 pm; N-Sn-N 176.8, C-SN-C 115.9-123.9, N-Sn-C 87.0-94.0-degrees.
