Abstract: The carboxylate dianion in the title compound, [Pb(C₁₄H₈O₅)(C₁₉H₁₂N₄O)₂]·2H₂O, uses one carboxylate group to O,O'-chelate a bis[4-(1H-1,3,7,8-tetraazacyclopenta[l]phenanthren-2-yl)phenol]-chelated Pb^II atom and uses its other carboxylate group to bind to another Pb^II atom in an irregular monodentate manner. The Pb^II atom exists in an undefined seven-coordinate geometry in the chain structure; the lone pair is stereochemically active. Adjacent chains are linked by intermolecular O-HN, N-HO and O-HO hydrogen bonds that involve the uncoordinated water molecules to form a three-dimensional network.
