| Popis: | In the title compound, [Pb2(C7H4O6S)2(C12H8N2)2(H2O)2]·CH3COOH, the seven-coordinate PbII atom is chelated by two N atoms of one 1,10-phenanthroline ligand, four O atoms from three 5-sulfosalicylate dianions and one water O atom. Each dianion serves as a bridging ligand, connecting adjacent PbII atoms into a centrosymmetric polymeric chain extending parallel to [001]. There are π–π interactions between the aromatic systems of neighbouring dianions, with plane-to-plane distances of 3.371 (2) Å, and between phenanthroline ligands, with a centroid-to-centroid distance of 3.484 (2) Å. O—H...O hydrogen bonding additionally stabilizes the crystal packing. The acetic acid molecules are incorporated in the voids of this arrangement. They exhibit half-occupancy due to disorder around a centre of inversion. |
