In the title compound, [RuCl2(C6H14N2)(C28H28P2)]·CH2Cl2, the RuII ion is coordinated in a slightly distorted octa­hedral environment, formed by two cis-oriented chloride ligands, two cis P atoms of a 1,4-bis­(diphenyl­phosphan­yl)butane ligand and two cis-chelating N atoms of a bidentate cyclo­hexane-1,2-diamine ligand. In the crystal, pairs of mol­ecules form inversion dimers via N—H⋯Cl hydrogen bonds. In addition, intra­molecular N—H⋯Cl and weak C—H⋯Cl, C—H⋯N, N—H⋯π and C—H⋯π hydrogen bonds are observed. One of the Cl atoms of the solvent mol­ecule is disordered over two sites with refined occupancies of 0.62 (1) and 0.38 (1).
