Poly[bis(μ3-naphthalene-1,4-dicarboxylato)(1,10-phenanthroline)dilead(II)

Abstract

In the title compound, [Pb2(C12H6O4)2(C12H8N2)] n or [Pb2(1,4-NDC)2(L)] n , where 1,4-NDC is naphthalene-1,4-dicarboxylate and L is 1,10-phenanthroline, the 1,4-NDC ligands link the PbII atoms into a layer structure. One Pb atom is ligated by L and also bonded to four 1,4-NDC O atoms and the other Pb atom bonds only to six 1,4-NDC O atoms. The lone pairs of the Pb atoms appear to be stereochemically active. Aromatic π–π stacking between L and 1,4-NDC ligands in adjacent layers helps to establish the packing [minimum centroid–centroid separation = 3.505 (3) Å].
