catena-Poly[[dimethyl-bis-(thio-cyanato-κN)tin(IV)]-μ-(4,4'-bipyridine-κN:N')].

The title dimethyl-tin diisothio-cyanate adduct of 4,4'-bipyridine, [Sn(CH(3))(2)(NCS)(2)(C(10)H(8)N(2))](n), adopts a chain motif in which the N-heterocycle functions as a bridge to adjacent all-trans octa-hedrally coordinated tin atoms. The Sn(IV) atom lies on a special position of 2/m site symmetry, the methyl C atom on a special position of 2 site symmetry, and the thio-cyanate and 4,4'-bipyridine on a special position of m site symmetry.
