Bis[bis­(4,4′-dimethyl-2,2′-bipyridine)(10,11,12,13-tetra­hydro­dipyrido[3,2-a:2′,3′-c]phenazine)ruthenium(II)] tetra­kis(perchlorate) acetonitrile disolvate monohydrate

The asymmetric unit of the title compound, [Ru(C(12)H(12)N(2))(2)(C(18)H(14)N(4))](2)(ClO(4))(4)·2CH(3)CN·H(2)O, contains two Ru(II) complex cations, four perchlorate counter-anions, two uncoord­inated acetonitrile mol­ecules and one water mol­ecule. The Ru(II) ions are chelated by one 10,11,12,13-tetra­hydro­dipyrido[3,2-a:2′,3′-c]phenazine (dpqc) and two 4,4′-dimethyl-2,2′-bipyridine (dmb) ligands in a distorted octa­hedral geometry. The uncoordinated water mol­ecule is disordered over three positions, with occupancy factors of 0.398 (9), 0.312 (8) and 0.290 (8). A supra­molecular structure is formed by weak π–π inter­actions between neighbouring mol­ecules, with face-to-face distances of 3.51 (1) Å [centroid–centroid distance 3.81 (1) Å].
