摘要

The reaction of Pb(CH3COO)(2)center dot 3H(2)O with N-benzesulfonyl-L-glutamic acid in the presence of 2, 2'-bipyridine (bipy) or 1,10-phenanthroline (phen) produced two novel complexes [Pb-2(Bs-glu)(2)(bipy)(2)] (1) and [Pb-2(Bs-glu)(2)(phen)(2)] (2) (Bs-glu = N-benzesulfonyl-L-glutamic acid dianion). In 1 chains bearing alternative 16-membered rings and Pb2O3 nodes are constructed from the interactions of Pb-II ions with the carboxylates of Bs-glu ligands. To the best of our knowledge, this is the first lead(II) complex of carboxylates with the formation of chains of Pb2O3, In 2 the 16-membered ring units are connected by centrosymmetric Pb2O2 nodes to form chains. Complexes 1 and 2 construct the 3-D supramolecular architectures through versatile hydrogen bonds and pi-pi stacking interactions.
