Abstract: In the title salt, [Zn(C22H24N4O)(CH3CN)][Zn(ClO4)(C22H24N4O)(CH3CN)](ClO4)3, two differently coordinated zinc cations occur. In the first complex, the metal ion is coordinated by the N,N',N'',O-tetradentate acetamide ligand and an acetonitrile N atom, generating an approximate trigonal-bipyramidal coordination geometry, with the O atom in an equatorial site and the acetonitrile N atom in an axial site. In the second complex ion, a perchlorate ion is also bonded to the zinc ion, generating a distorted trans-ZnO2N4 octahedron. Of the uncoordinating perchlorate ions, one lies on a crystallographic twofold axis and one lies close to a twofold axis and has a site occupancy of 0.5. N-H...O and N-H...(O,O) hydrogen bonds are observed in the crystal. Disordered solvent molecules occupy about 11% of the unit-cell volume; their contribution to the scattering was removed with the SQUEEZE routine of the PLATON program [Spek (2009). Acta Cryst. D65, 148-155.].
