Abstract
Abstract Based on asymmetric lithium salt of 1-(4-pyridinylmethyl)-1H-1,2,4-triazole-3-carboxylic acid ligand (pmtcLi), five Pb(II)-containing polymers [Pb(pmtc)(OAc)]n (1), [Pb(pmtc)(Cl)]n (2), [Pb(pmtc)(Br)]n (3), [Pb(pmtc)(I)]n (4) and {[Pb(pmtc)2(H2O)3]·H2O}n (5) have been hydrothermally synthesized and structurally characterized. 1-4 display 2D networks, in which 1 and 2 present (4.82) topology, whereas 3 and 4 show (44.62) topology, respectively. 5 is a 1D chain structure. The counter anions have an important influence on their structures and photoluminescent properties. Through calculations of the frontier molecular orbital (FMOs) of 1-5, their photoluminescence should be attributed to the n→π* transition.
