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-HBr hydrogen bonds, forming a centrosymmetric diamond-shaped R42(8) motif. The cation and anions and the solvent molecules are linked via C-HF, C-HBr, C-HCl and C-HO hydrogen bonds, forming a three-dimensional network.
