Di-μ-acetato-1:2κ2O:O′;2:3κ3O:O,O′-bis(5,5,7,12,12,14-hexamethyl-1,4,8,11-tetraazacyclotetradecane)-1κ4N,3κ4N-bis(perchlorato-2κ2O,O′)-2-sodium-1,3-dizinc perchlorate

Abstract

In the title salt, [NaZn2(CH3COO)2(ClO4)2(C16H36N4)2]ClO4, the macrocyclic ligand binds to the Zn2+ cations through their four amino N atoms; the Zn2+ cations are also each covalently bonded to an acetate ion. For one zinc atom, the acetate group is monodentate, and the geometry is a distorted ZnN4O trigonal bipyramid; for the other, the acetate group is anisobidentate and the geometry is a distorted ZnN4O2 octahedron. The two macrocycle–zinc acetate units are bridged through a diperchloratosodium unit. In the crystal, the complex cations and uncoordinated perchlorate anions are linked by N—H...O hydrogen bonds.
