Crystal structures of the water and acetone monosolvates of bis­4′-(pyridin-4-yl)-22′:6′2′′-terpyridine­manganese(II) bis­(hexa­fluorido­phosphate)

摘要

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 Mn^II 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.
