Reactions of the poly-pyridyl bridging ligand 2,4,6-tris(2-pyridyl)-1,3,5-triazine; 2,3-bis(2-pyridyl)-pyrazine and 3,6-bis(2-pyridyl)-1,2,4,5-tetrazine (referred hereafter as tptz, bppz and bptz respectively) with [RuH(CO)Cl(PPh3)3] in methanol, gave highly stable cationic complexes with the formulation [RuH(CO)(PPh3)2(L)]+. Further, the mononuclear complex [RuH(CO)(PPh3)2(bppz)]PF6 reacted with K2PtCl4, [PdCl2(benzonitrile)2], [RuH(CO)(PPh3)2(bppz)PdCl2]PF 6, [RuH(CO)(PPh3)2(bppz)(η 6-C10 H14)RuCl](PF6) 2, [RuH(CO)(PPh3) 2(bppz)(η 6-C6Me6)Cl2Ru](PF 6)2, [RuH(CO)(PPh3)2 (bppz)(η5-C5H5) (PPh 3)Ru](PF6)2 and [RuH(CO)(PPh 3)2(bppz)Rh(η5-C5 Me5)Cl](PF6)2 in quantitative yield. The reaction products have been characterized by elemental analyses, IR, 1H-, 1H-1H-COSY, 13C-, 31P-NMR, ESMS, FAB mass spectroscopy, electronic spectra and cyclic voltammetry. Molecular structure of the representative mononuclear complex [RuH(CO)(PPh3)2(tptz)]BF4 has been confirmed by X-ray crystallography. Crystal structure determination revealed η2-coordination of the ligand tptz with the metal center. Crystal data: monoclinic, P21/n, a = 17.810(6) A?, b = 22.233(9) A?, β = 90.06(3)°, Z = 4, R = 0.078.
