    Summary
    The mononuclear cations of the general formula [(η6-arene)RuCl(pdpt)]+ (pdpt = 5,6-diphenyl-3-(pyridine-2-yl)-1,2,4-triazine; arene = C6H6 (1); C6H5Me (2); p-PriC6H4Me (3); C6Me6 (4)) have been synthesised from 5,6-diphenyl-3-(pyridine-2-yl)-1,2,4-triazine (pdpt) and the corresponding chloro complexes [(η6-C6H6)Ru(μ-Cl)Cl] 2, [(η6-C6H5Me)Ru(μ-Cl)Cl]2, [(η6p-PriC6H4Me)Ru(μ-Cl)Cl]2 and [(η6-C6Me6)Ru(μ-Cl)Cl]2, respectively. The X-ray crystal structure analyses of [1][PF6] • (C6H6)2.5 and [2][PF6] • (CH3CN)2 reveal a typical piano-stool geometry around the metal centre and in the crystal packing a complexed networks of intermolecular interactions.
