In the title salt, [NaZn 2 (CH 3 COO) 2 (ClO 4 ) 2 (C 16 H 36 N 4 ) 2 ]ClO 4 , the macrocyclic ligand binds to the Zn 2+  cations through their four amino N atoms; the Zn 2+  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 ZnN 4 O trigonal bipyramid; for the other, the acetate group is anisobidentate and the geometry is a distorted ZnN 4 O 2  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.
