    In the title compound, [RuCl(C15H11N3)(C12H8N2O4)]ClO4 center dot C2H5OH center dot H2O, the geometry of the ClN5 coordination set around the Ru-II atom is close to octahedral, but distorted on account of the limited bite angles of the polypyridyl ligands. The complexes are linked by O-H center dot center dot center dot O hydrogen bonds between the carboxyl groups and the crystal lattice water molecules into chains along [110]. Face-to-face stacking interactions are formed between terpyridine ligands, with interplanar separations of 3.66 (1) and 3.42 (1) angstrom, and between bipyridine-4,4 '-dicarboxylic acid ligands, with interplanar separations of 3.65 (1) and 3.72 (1) angstrom. Three O atoms of the perchlorate ion are each disordered equally over two positions. The hydroxy group of the ethanol molecule is also disordered over two sites with refined occupancies of 0.794 (9) and 0.206 (9).
