Abstract: The title compound, [Zn₂(NO₃)₂(C₂₂H₃₀N₄O₂)], is a centrosymmetric dinuclear zinc compound. Each Zn atom has a square-pyramidal geometry with N₂O₃ donors, being coordinated by two N atoms and two O atoms from the macrocyclic 10,21-dimethyl-3,6,14,17-tetraazatricyclo[17.3.1^8,12]tetracosa-1(23),8,10,12(24),19,21-hexaene-23,24-diolate ligand and one O atom from a nitrate anion. In the structure, two Zn atoms are linked by two phenolate O atoms to give a four-membered Zn₂O₂ ring.
