Tris(4,4'-bipyrimidine)ruthenium(II) Bis(hexafluorophosphate) Acetone Solvate

The molecular structure of tris(4,4'-bipyrimidine)ruthenium(II) {[Ru(bpm)₃]²⁺} in the title compound {[Ru(C₈H₆N₄)₃](PF₆)₂.C₃H₆O} is similar to that of tris(2,2'-bipyridine)ruthenium(II) {[Ru(bpy)₃]²⁺}. However, replacement of C by N in the heterocyclic ring alters the molecular electrostatic potential of the complex cation and hence the chiral recognition and self-assembling, yielding a crystal packing pattern that is unique among known structures of related trisdiimine-metal complexes.
