Triethylenetetraminehexaacetic Acid Complex of Lead

Abstract

In the title compound, tetrasodium μ-[3,6,9,12-tetrakis(carboxymethyl)-3,6,9,12- tetraazatetradecandioato-1κ5O1,N3,O3,N6, O6:2κ5N9,O9,N12,O12,O14]dilead dinitrate decahydrate, Na4[Pb2(C18H24N4O12)](NO3)2.10H2O, the Pb2+ ions have highly distorted bonding geometry, with a primary coordination number of five and two secondary intermolecular contacts. The Pb—N bond distances range from 2.505 (4) to 2.641 (4) Å, and the Pb—O bond distances range from 2.454 (3) to 2.559 (3) Å. The binuclear lead complexes sit on inversion centers and are bridged to form polymeric structures. The poymers are linked into sheets via N⋯O contacts.
