The reaction of a series of readily available extended terpyridyl and extended triazine ligands with several d6-metal centres has been investigated. This has led to the isolation and characterisation of nine new complexes, one of which is the first reported transition metal complex to contain the 2,4,6-tris(2-pyrimidyl)-1,3,5-triazine (tpymt) ligand. Two of the new complexes have had their molecular structures confirmed via X-ray crystallography studies. It has been shown that changes in the electronic properties of the coordinated ligand results in modulation of the electrochemical and photophysical properties of the complex to which it is coordinated. Furthermore, the emission properties of extended terpyridyl complexes incorporating the [Re(CO)3(MeCN)]+ centre suggest that luminescence in these complexes is from an extended terpyridyl based intraligand state.
The triplatinum complex of the 2,4,6-Tris(2-pyrimidyl)-1,3,5-triazine ligand, Pt3TPymT hereafter, has been prepared and characterized for the first time. NMR studies point out that the three platinum(II) centers possess an identical coordination environment. The interactions of Pt3TPymT with DNA were explored in comparison to the free ligand. Specifically, fluorescence, mass spectrometry, viscometry
