Bis(2-fluorobenzoato-κ2O,O′)bis(1,10-phenanthroline-κ2N,N′)lead(II) dihydrate

Abstract

In the title compound, [Pb(C7H4FO2)2(C12H8N2)2]·2H2O, the PbII atom is coordinated by four N atoms from two bidentate chelating 1,10-phenanthroline (phen) ligands and four O atoms from two 2-fluorobenzoate ligands in an irregular polyhedral coordination geometry. Two carboxylate O atoms and one F atom are each disordered over two sites with occupancy factors of 0.60 and 0.40. The dihedral angle between the two phen ligands is 89.9 (1)°. The mean interplanar distances are alternatively of 3.44 (3) and 3.45 (3) Å, indicating π–π stacking interactions between the neighboring phen ligands. In the crystal, O—H...O, O—H...F and C—H...O hydrogen bonds link the complex molecules and uncoordinated water molecules into a supramolecular network.
