(4-Aminopyridine-κN1)(2,2′-bipyridine-κ2N,N′)(2,2′:6′,2′′-terpyridine-κ3N,N′,N′′)ruthenium(II) bis(hexafluoridophosphate) unknown solvate

Abstract

The title compound, [Ru(C5H6N2)(C10H8N2)(C15H11N3)](PF6)2 solvent, crystallizes in the triclinic space group P\overline{1} with one dicationic Ru complex, two PF6− anions, and undefined solvent in the asymmetric unit. The cation and anions are linked via N—H...F hydrogen bonding. One PF6− anion is disordered over two positions, with occupancies 0.634 (8) and 0.366 (8). The solvent, which is located in channels in the crystal, is highly disordered. Reflection contributions from the solvent were added to the calculated structure factors using the SQUEEZE routine [Spek (2015) Acta Cryst. C71, 9–18] of the program PLATON, which determined there to be 59 electrons in 264 Å3 treated this way per unit cell. Because the exact identity and amount of solvent were unknown, no solvent was included in the atom list or molecular formula.
