Crystal structures of the water and acetone monosolvates of bis[4′-(pyridin-4-yl)-2,2′:6′,2″-terpyridine]manganese(II) bis(hexafluorido-phosphate)

Abstract

The crystal structures of bis[4′-(pyridin-4-yl)-2,2′:6′,2″-terpyridine]mangan-ese(II) bis(hexafluoridophosphate) monohydrate, [Mn(C20H14N4)2](PF6)2·-H2O, (1), and bis[4′-(pyridin-4-yl)-2,2′:6′,2″-terpyridine]manganese(II) bis-(hexafluoridophosphate) acetone monosolvate, (2), [Mn(C20H14N4)2]-(PF6)2·CH3COCH3, are described. At 150 K, (1) and (2) have monoclinic (P21/c) and orthorhombic (C2221) symmetries, respectively. Both structures exhibit octahedrally coordinated MnII atoms and disorder. They display weak interactions, such as C - H⋯F, C - H⋯N, C - H⋯π, F⋯π and π-π. The twofold rotation axis in the molecule of (2) is coincident with a twofold rotation axis of the crystal.
