Abstract: In the title complex, [Ru(C12H8N2)2(C5H6N2)2](PF6)2, the RuII 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...F hydrogen-bonding interactions play an important role in the crystal assembly: 21-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...[pi] contacts (H...centroid = 3.45 Å) are responsible for cross-linking between the helical chains along [001].
