Abstract
We report cytotoxic ruthenium(ii) complexes of the general formula [RuCl(cis-tach)(diphosphine)]+ (cis-tach = cis-cis-1,3,5-triaminocyclohexane) that have been characterised by 1H, 13C and 31P{1H} NMR spectroscopy, mass spectrometry, X-ray crystallography and elemental analysis. The kinetics of aquation and stability of the active species have been studied, showing that the chlorido ligand is substituted by water at 298 K with first order rate constants of 10-2-10-3 s-1, ideal for potential clinical use as anti-tumour agents. Strong interactions with biologically relevant duplex and quadruplex DNA models correlate with the activity observed with A549, A2780 and 293T cell lines, and the degree of activity was found to be sensitive to the chelating diphosphine ligand. A label-free ptychographic cell imaging technique recorded cell death processes over 4 days. The Ru(ii) cis-tach diphosphine complexes exhibit anti-proliferative effects, in some cases outperforming cisplatin and other cytotoxic ruthenium complexes.

Abstract
The chemistry of NHCcore pincer ligands of LX2 type bearing two pending arms, identical or not, whose coordinating center is anionic in nature, is here reviewed. In this family, the negative charge of the coordinating atoms can be brought either by a carbon atom via a phosphonium ylide (R3P+-CR2-) or by a heteroatom through amide (R2N-), oxide (RO-), or thio(seleno)oxide (RS-, RSe-) donor functionalities. Through selected examples, the synthetic methods, coordination properties, and applications of such tridentate systems are described. Particular emphasis is placed on the role of the donor ends in the chemical behavior of these species.

Abstract
The title trinuclear ruthenium cluster, [Ru3(C30H24P2)(C9H11P)(CO)7(μ-H)2], has a triangular Ru3core that is capped with a mesitylphosphinidene ligand, μ3-PMes (Mes = mesityl = 2,4,6-trimethylphenyl). The 1,2-bis(diphenylphosphanyl)benzene molecule acts as a bidentate phosphine ligandviatwo P atoms connecting to a single Ru atom. The title compound crystallizes with two independent molecules in the asymmetric unit.
