Two lead(II) 2,4-dioxo-1,2,3,4-tetrahydropyrimidine-5-carboxylate complexes exhibiting different topologies and fluorescent properties
Abstract
The reactions of PbCl{sub 2} with 2,4-dioxo-1,2,3,4-tetrahydropyrimidine-5-carboxylic acid (H{sub 3}iso) gave two complexes [Pb(H{sub 2}iso){sub 2}(H{sub 2}O)]{sub n} (1) and [Pb(Hiso)(H{sub 2}O)]{sub 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 Schlaefli symbol (4.8{sup 5})(4.8{sup 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 Schlaefli symbol (4.8{sup 2})(4.8{sup 2}) based on the calculation of only the normal Pb-O bonds and a 5,5-connected 3D network with the Schlaefli symbol (4{sup 15}.6{sup 4})(4{sup 4}.6{sup 8}.8{sup 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. -- Graphical abstract: The reactions of PbCl{sub 2} with 2,4-dioxo-1,2,3,4-tetrahydropyrimidine-5-carboxylic acid (H{sub 3}iso) gave two complexes [Pb(H{sub 2}iso){sub 2}(H{sub 2}O)]{sub n} (1) and [Pb(Hiso)(H{sub 2}O)]{sub n} (2), which display different topologies and fluorescent properties.
