The crystal structure of the title compound, bis(2,2': 6',2''-terpyridine)r
uthenium(II) bis(hexafluorophosphate) diacetonitrile solvate, with the comp
osition [Ru(C15H11N3)(2)](PF6)(2). 2C(2)H(3)N is described. The pseudo-octa
hedral Ru complex has a C-2 nu point symmetry, imposed by the geometry cons
traints of the two identical tridentate ligands. The tetragonal unit cell,
with its remarkably long c axis [49.306(3)Angstrom], contains two symmetry-
independent formula units.
