Deskripsi
In the title compound, [Zn2(C36H42N4O2)(CH3COO)2]·2CH3CH2OH, a centrosymmetric dinuclear zinc macrocyclic complex is accompanied by two half-occupied ethanol solvent molecues resulting in a 1:2 macrocycle–solvent composition. The ZnII atom has a square-pyramidal geometry arising from an N2O3 donor set, being coordinated by two N atoms and two O atoms from the macrocyclic ligand in the equatorial sites and one O atom from an acetate anion in the apical site. The two ZnII atoms are linked by two phenolate O atoms, generating a four-membered Zn2O2 ring at the centre of the macrocycle. The tert-butyl group shows rotational disorder over two sets of sites in a 0.552 (12):0.448 (12) ratio. In the crystal, N—H...O and O—H...O hydrogen bonds are seen and a short intramolecular C—H...O contact occurs.
