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 and C-H 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).
