A salen-type trinuclear Zn2Gd complex

Abstract

In the trinuclear title complex, di-μ-acetato-1:2κ2 O:O′;2:3κ2 O:O′-bis­{μ-6,6′-dimeth­oxy-2,2′-[cyclo­hexane-1,2-diylbis(methanylyl­idene)]diphenolato}-1:2κ6 O 1,N,N′,O 1′:O 6,O 6′;2:3κ6 O 6,O 6′:O 1,N,N′,O 1′-2-gadolinium(III)-1,3-dizinc hexa­fluor­idophosphate methanol monosolvate monohydrate, [GdZn2(C22H24N2O4)2(CH3COO)2]PF6·CH3OH·H2O, the two ZnII ions are located in the inner N2O2 cavities of two 6,6′-dimeth­oxy-2,2′-[cyclo­hexane-1,2-diylbis(methanylyl­idene)]diphenolate (L) ligands. Both ZnII ions are five-coordinated by two O atoms and two N atoms from the L ligand and one O atom of an acetic acid mol­ecule, giving rise to a square-pyramidal geometry around the ZnII ions. The GdIII ion is nine-coordinated by four O atoms from the outer O2O2 sites of one ligand, and three O atoms from another ligand, in which there is one non-coordinating meth­oxy O atom. Two further O atom from different acetate ligands complete the nine-coordinate environment.
