Abstract: In the cation of the title complex, [Ru(C31H32N3P2)(C10H8N2)2](PF6)(Br)2·2CH2Cl2·H2O, the ruthenium ion is coordinated in a distorted octa­hedral geometry by two 2,2'-bi­pyridine (bpy) ligands and a chelating cationic N-di­phenyl­phosphino-1,3,4,6,7,8-hexa­hydro-2-pyrimido[1,2-a]pyrimidine [(PPh2)2-hpp] ligand. The tricationic charge of the complex is balanced by two bromide and one hexa­fluorido­phosphate counter-anions. The compound crystallized with two mol­ecules of di­chloro­methane (one of which is equally disordered about a Cl atom) and a water mol­ecule. In the crystal, one of the Br anions bridges two water mol­ecules via O-H...Br hydrogen bonds, forming a centrosymmetric diamond-shaped R42(8) motif. The cation and anions and the solvent mol­ecules are linked via C-H...F, C-H...Br, C-H...Cl and C-H...O hydrogen bonds, forming a three-dimensional network.
