Bottom Line: In the second complex ion, a perchlorate ion is also bonded to the zinc ion, generating a distorted trans-ZnO(2)N(4) octa-hedron.Acta Cryst.D65, 148-155.].

ABSTRACT
In the title salt, [Zn(C(22)H(24)N(4)O)(CH(3)CN)][Zn(ClO(4))(C(22)H(24)N(4)O)(CH(3)CN)](ClO(4))(3), two differently coordinated zinc cations occur. In the first complex, the metal ion is coordinated by the N,N',N'',O-tetra-dentate 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-ZnO(2)N(4) octa-hedron. 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 mol-ecules 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.].

Octahedral geometry at Zn1A (left) and trigonal bipyramidal geometry at Zn1B (right). In-plane bond angles (°) have been indicated. N3—Zn1—N4 undergoes an opening of 27.4° from B to A to accommodate the extra perchlorate ligand O1D. In both complexes the N5—Zn1—N3/N4/O1 angles are slightly larger than the N2—Zn1—N3/N4/O1 angles, with ranges 96.0 - 102.8° and 78.7 - 80.3°, respectively.
