The compound [(Cu(PPh(3))(2))(3)(HATNMe(6))](BF(4))(3) has been synthesized and characterized by X-ray crystallography, resonance Raman spectroscopy, and density functional theory (DFT) calculations. The X-ray structure of solvated [(Cu(PPh(3))(2))(3)(HATNMe(6))](BF(4))(3) [rhombohedral, R3, a = b = 21.6404(4) A, c = 53.188(3) A, alpha = beta = 90 degrees,(More)
Heterodinuclear ruthenium(II)-cobalt(III) complexes have been prepared as part of investigations into a new approach to selective cancer treatment. A cobalt(III) centre bearing amine ligands, which serve as models for cytotoxic nitrogen mustard ligands, is connected by a bridging ligand to a ruthenium(II)-polypyridyl moiety. Upon excitation of the ruthenium(More)
A new family of ruthenium(II) complexes with multichromophoric properties was prepared based on a "chemistry-on-the-complex" synthetic approach. The new compounds are based on tridentate chelating sites (tpy-type ligands, tpy=2,2':6',2''-terpyridine) and most of them carry appended anthryl chromophores. Complexes 2 a and 2 b were synthesized through the(More)
The dinuclear ruthenium complex of a large, planar bis-tridentate bridging ligand has been prepared; to the best of our knowledge, this species is the near IR-emitting Ru(II) complex exhibiting the longest-lived emission and highest quantum yield reported so far, due to the dramatic reduction in its radiationless decay rate constant.
The first example of an iridium biscyclometalated complex with a C wedge N wedge C 2,6-diphenylpyridine (dppy)-type ligand, [(4'-(4-bromophenyl)-2:2',6':2' '-terpyridine)Ir(2,6-diphenyl-4-(4-tolyl)pyridine)](NO(3)) (1), has been synthesized and characterized by various techniques such as X-ray crystallography, mass spectrometry, (1)H and (13)C NMR, cyclic(More)
The rod-like binuclear complexes [(ttpy)Ru(tpy-ph(2)-phbpy)Ru(ttpy)](4+) and [(ttpy)Ru(tpy-ph(2)-tpy)Ru(phtbpy)](4+) (for abbreviations, see text) have been synthesized and characterized. In both complexes, the polypyridine Ru(II) centers have (N--N--N)Ru(N--N--N) and (N--N--N)Ru(C--N--N) coordination environment. The two isomeric species differ in whether(More)
The asymmetric unit of the title compound, [Ru(C19H13N5)2](PF6)2, consists of an Ru II complex cation and two hexafluoridophosphate anions. The Ru atom is coordinated by three N atoms from the two outer pyridine and the central triazine rings of each of two tridentate ligands in a distorted octahedral environment. The ligands are approximately orthogonal to(More)
In the title compound, [RuCl(C(6)H(6))(C(10)H(8)N(2))]Cl·1.5CH(4)O, the Ru(II) atom is in a distorted octa-hedral environment coordinated by an η(6)-benzene ring, a chelating 2,2'-bipyridine ligand and a chloride ion. The asymmetric unit is completed by a chloride anion and two methanol mol-ecules, one of which is disordered about a centre of inversion with(More)
A family of tridendate ligands 1 a-e, based on the 2-aryl-4,6-di(2-pyridyl)-s-triazine motif, was prepared along with their hetero- and homoleptic Ru(II) complexes 2 a-e ([Ru(tpy)(1 a-e)](2+); tpy=2,2':6',2"-terpyridine) and 3 a-e ([(Ru(1 a-e)(2)](2+)), respectively. The ligands and their complexes were characterized by (1)H NMR spectroscopy, ES-MS, and(More)
