Cationic ruthenium complexes based on planar polypyridyl ligand 2,4,6-tris (2-pyridyl)-1 ,3,5-triazine

Abstract

2573-2577New cationic complexes [RU(κ3-tptz){(p-FC6H4)3P}2Cl]BF4, [RU(κ3-tptz){ (p-CH3C6H4)3P}2Cl] BF4, [RU(κ3-tptz){ (p-ClC6H4)3P}2 Cl] BF4, [RU(κ3-tptz){(p-CH3OC6H4)3P}2Cl]BF4, and [RU(κ3-tptz){(p-(CH3)2NC6H4)3P}2Cl]BF4 containing both group 15 donor and a planar polypyridyl ligand are prepared by reaction of RuCIJ.xH20 with an excess amou nt of phosphines and 2,4,6-tris(2-pyridyl)-1 ,3,5- triazine (tptz) in methanol under refluxing conditions. The complexes have been characterized by elemental analyses and spectral techniques, viz .. IR, 1H NMR, 31P NMR, FAB-MS and electronic spectral studies
