Synthesis and crystal structure of [Pb(trz)(tfpb)(H2O)]: a lead(II) complex containing 2,4,6-tris(2-pyridyl)-1,3,5-triazine and 4,4,4-trifluoro-1-phenyl-1,3-butandionate

[Pb(trz)(tfpb)(H2O)] (1) (trz and tfpb are the abbreviations of 2,4,6-tris(2-pyridyl)-1,3,5-triazine and 4,4,4-trifluoro-1-phenyl-1,3-butandionate, respectively) have been synthesized and characterized by elemental analysis and IR, H-1 NMR, spectroscopy. The single-crystal structure of 1 shows the coordination number of the Pb2+ ions is eight with three N-donor atoms from a trz ligand and four O-donors from the dionate ligand and one molecule of water. The supramolecular features in this complex are guided by lone pair activity and control of strong hydrogen bonds, weak directional intermolecular interactions and aromatic pi-pi stacking interactions.
