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.].

(a) The asymmetric unit with H atoms omitted for clarity. C atoms in molecule A (including the associated acetonitrile ligand) are shown in light grey colour, as opposed to C atoms in molecule B which are dark grey. O atoms in perchlorate ion D, coordinating to molecule A, appear in orange, while O atoms in perchlorate ion E close to B are dark red. Perchlorate ions F and G are depicted here as light green and green spheres, respectively, to reduce overlap with A and B. (b) Complex A with perchlorate D. One pyridine ring has been shaded.
