The synthesis and characterisation of nonclassical ruthenium hydride complexes containing bidentate PP and tridentate PCP and PNP pincer‐type ligands are described. The mononuclear and dinuclear ruthenium complexes presented have been synthesised in moderate to high yields by the direct hydrogenation route (one‐pot synthesis) or in a two‐step procedure. In both cases [Ru(cod)(metallyl) 2 ] served as a readily available precursor. The influences of the coordination geometry and the ligand framework on the structure, binding, and chemical properties of the MH 2 fragments were studied by X‐ray crystal structure analysis, spectroscopic methods, and reactivity towards N 2 , D 2 , and deuterated solvents.
