The crystal structures of bis[4'-(pyridin-4-yl)-2,2':6',2 ''-terpyridine]manganese(II) bis(hexafluoridophosphate) monohydrate, [Mn(C20H14N4)(2)](PF6)(2)center dot-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)center dot CH3COCH3, are described. At 150 K, (1) and (2) have monoclinic (P2(1)/c) and orthorhombic (C222(1)) symmetries, respectively. Both structures exhibit octahedrally coordinated Mn-II atoms and disorder. They display weak interactions, such as C-H center dot center dot center dot F, C-H center dot center dot center dot N, C-H center dot center dot center dot pi, F center dot center dot center dot pi and pi-pi. The twofold rotation axis in the molecule of (2) is coincident with a twofold rotation axis of the crystal.
