In the title compound, [Ni(C16H28N4)](ClO4)(2), all the Ni-N distances are
approximately equal [1.896(3)1.904 (2) Angstrom]. There is no direct intera
ction between the Ni atoms and the perchlorate ions. Although most C ... O
interactions are close to or insignificantly less in size than those expect
ed for van der Waals packing, one was found to be 3.105 (7) Angstrom.
