Abstract

The reaction of lead acetate, benzoic acid and 1,10-phenanthroline (phen) in aqueous solution yielded the title complex, [Pb(C7H5O2)2(C12H8N2)]·C7H6O2. In the crystal, the PbII ion is hexacoordinated by two N atoms from one 1,10-phenanthroline ligand and four O atoms from two chelate benzoate anions. If the second benzoate ligand is treated as one coordination site, the overall coordination may be represented as a distorted pseudo-square pyramid. An intermolecular O—H⋯O hydrogen bond links the solvent benzoic acid molecule with a metal-coordinated benzoate ligand. The shortest Pb⋯Pb distance is 3.864 (4) Å, indicating a weak metal–metal interaction. Two complex molecules related by an inversion centre form dimeric units via Pb⋯O interactions of 3.206 (4) Å.
