A salen-type trinuclear Zn2Gd complex.

In the trinuclear title complex, di-μ-acetato-1:2κ(2)O:O';2:3κ(2)O:O'-bis-{μ-6,6'-dimeth-oxy-2,2'-[cyclo-hexane-1,2-diylbis(methanylyl-idene)]diphenolato}-1:2κ(6)O(1),N,N',O(1'):O(6),O(6');2:3κ(6)O(6),O(6'):O(1),N,N',O(1')-2-gadolinium(III)-1,3-dizinc hexa-fluor-idophosphate methanol monosolvate monohydrate, [GdZn2(C22H24N2O4)2(CH3COO)2]PF6·CH3OH·H2O, the two Zn(II) ions are located in the inner N2O2 cavities of two 6,6'-dimeth-oxy-2,2'-[cyclo-hexane-1,2-diylbis(methanylyl-idene)]diphenolate (L) ligands. Both Zn(II) ions are five-coordinated by two O atoms and two N atoms from the L ligand and one O atom of an acetic acid mol-ecule, giving rise to a square-pyramidal geometry around the Zn(II) ions. The Gd(III) 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 meth-oxy O atom. Two further O atom from different acetate ligands complete the nine-coordinate environment.
