Abstract

In the title complex, [Ru(C12H8N2)(2)(C5H6N2)(2)](PF6)(2), the Ru-II atom is bonded to two alpha-diimine ligands, viz. 1,10-phenanthroline (phen), in a cis configuration, in addition with with two 4-aminopyridine (4Apy) ligands, resulting in a distorted octahedral coordination geometry. N-H center dot center dot center dot F hydrogen-bonding interactions play an important role in the crystal assembly: 2(1)-screw-axis-related complex molecules and PF6- counter-ions alternate in helical chains formed along the a axis by means of these contacts. N-H center dot center dot center dot pi contacts (H center dot center dot center dot centroid = 3.45 angstrom) are responsible for cross-linking between the helical chains along [001]. (AU)
