Re-investigation of lead(II) formate crystal structure.

The crystal structure of the title compound, poly[di-?4-formato-lead(II) ], [Pb(HCOO)2] n , has been re-investigated. It consists of a three-dimensional polymeric network of Pb2+ nodes connected by bridging formate anions. Despite having been described previously, the structural information available so far [Harrison & Steel (1982). J. Organomet. Chem. 239, 105-113] is incomplete and the reported Pnma space group is incorrect. In this work, the space-group assignment to P212121 is discussed and a complete description of the structural features of lead(II) formate is provided.
