Bis(benzoato-κ(2) O,O′)(1,10-phenanthroline-κ(2) N,N′)lead(II) benzoic acid mono­solvate

The reaction of lead acetate, benzoic acid and 1,10-phenanthroline (phen) in aqueous solution yielded the title complex, [Pb(C(7)H(5)O(2))(2)(C(12)H(8)N(2))]·C(7)H(6)O(2). In the crystal, the Pb(II) 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.
