metal-organic compounds
The title compound, [Ni2Zn(C24H22N4O6)2(CH4O)2](ClO4)2, was synthesized using a mononuclear complex ligand NiL (L is diethyl 5,6,7,8,15,16-hexahydro-6,7-dioxo-5,8,14,17-tetraazadibenzo[a,g]cyclotetradecine-13,18-dicarboxylate), Zn(ClO4)2·6H2O and CH3OH. X-ray single-crystal analysis reveals that the Zn2+ ion is in a slightly distorted octahedral O6 environment. The trinuclear complex cation is centrosymmetric. The Zn2+ and both Ni2+ ions are bridged by the oxamide group from the macrocyclic ligand L. Intermolecular O—HO hydrogen bonds exist between the perchlorate anion and the complex cation, and π–π interactions organize the trinuclear cations to form supramolecular one-dimensional chains in the crystal structure.

In the title complex, [Cu(C22H18N4O6)], the CuII atom is coordinated by four N atoms from a macrocyclic ligand with a square-planar geometry. Weak C—HO hydrogen bonding occurs between neighbouring CuII complexes in the crystal structure.
