Abstract: In the trinuclear title complex, di-[mu]-acetato-1:2[kappa]2O:O';2:3[kappa]2O:O'-bis{[mu]-6,6'-dimethoxy-2,2'-[cyclohexane-1,2-diylbis(methanylylidene)]diphenolato}-1:2[kappa]6O1,N,N',O1':O6,O6';2:3[kappa]6O6,O6':O1,N,N',O1'-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.
