Poly[trans-bis{trimethyltin(IV)}-μ-(2,2'-bipyridyl-4,4'-dicarboxylato-O:O':O'':O''')]. A Layered Structure Composed of Sheets Interconnected by Organometallic Moieties

In the solid state, the title compound, [Sn₂(C₁₂H₆N₂O₄)(CH₃)₆], forms a two-dimensional polymer, which is developed parallel to the crystallographic 2₁ screw axis of the P2₁/n space group. The Sn atom shows a normal trans pentagonal-bipyramidal coordination geometry and forms two bonds of different length, 2.145 (2) and 2.519 (2) Å, with the two trans O atoms. The carboxylate group bonds two organometallic moieties in a bridging bidentate fashion with a syn–anti configuration.
