In the centrosymmetric mol­ecular structure of the title compound [Pt2(C6H14P)2H2(C9H21P)2], each PtII atom is bound on one side to a phosphane ligand (PiPr3) and a hydrido ligand. On the other side, it is bound to two phosphanide ligands (μ-PiPr2), which engage a bridging position between the two PtII atoms, forming a distorted square-planar structure motif. The Pt⋯Pt distance is 3.6755 (2) Å. A comparable mol­ecular structure was observed for bis­(μ-di-tert-butyl­phosphanido)bis­[hydrido(triethyl­phosphane)platinum(II)] [Itazaki et al. (2004 ▶). Organometallics, 23, 1610–1621].
