摘要：

The reactions of PbCl2 with 2,4-dioxo-1,2,3,4-tetrahydropyrimidine-5-carboxylic acid (H(3)iso) gave two complexes [Pb(H(2)iso)(2)(H2O)](n) (1) and [Pb(Hiso)(H2P)](n). (2), which were characterized by IR spectroscopy, elemental analysis, thermogravimetric analysis, powder X-ray diffraction and single crystal X-ray diffraction analysis. The two complexes display different topologies. 1 shows a three-dimensional framework with the Schlafli symbol (4.8(5))(4.8(2)) no matter if the weak Pb-O bonds are included or not. However, 2 presents a 3,3-connected two-dimensional sheet with the Schlafli symbol (4.8(2))(4.8(2)) based on the calculation of only the normal Pb-O bonds and a 5,5-connected 3D network with the Schlafli symbol (4(15).6(4))(4(4).6(8).8(2)) when the weak Pb-O bonds are also included. The fluorescent studies reveal an emission attributed to intraligand emission for 1 and an emission assigned to LMCT for 2. (C) 2011 Elsevier Inc. All rights reserved.
