Abstract
Pb(II) and Cd(II) complexes, {[Pb2(PDTS)2(CH3OH)((H2O)2]⋅ H2O} n (1) and [Cd(PDTS)(H2O)4]⋅ 2H2O (2) (PDTS2− = 3-(2-pyridyl)-5,6-diphenyl-1,2,4-triazine-p,p′-disulfonate), are synthesized and characterized by elemental analysis, infrared (IR), 1H-NMR spectroscopy, and thermal analysis. The single-crystal structure of 1 shows that the complex forms a 2-D polymeric network containing two types of Pb2+ with coordination number eight (PbN2O6). Both possess hemidirected coordination geometries. The single-crystal structure of 2 shows distorted octahedral geometry for cadmium(II), CdN2O4. These compounds are the first complexes of “PDTS2−”. The supramolecular features in these complexes are guided/controlled by hydrogen bonding and noncovalent intermolecular interactions.
