crystal structures of the water and acetone monosolvates of bis[4′-(pyridin-4-yl)-2,2′:6′,2′′-terpyridine]manganese(ii) bis(hexafluoridophosphate)

The crystal structures of bis[4′-(pyridin-4-yl)-2,2′:6′,2′′-terpyridine]manganese(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.
