μ-Acetato-κ(2) O:O′-[7,23-dibenzyl-15,31-dichloro-3,7,11,19,23,27-hexa­azatri­cyclo­[27.3.1.1(13,17)]tetra­triconta-1(32),2,11,13,15,17(34),18,27,29(33),30-deca­ene-33,34-diolato-κ(10) N (4),N (5),N (6),O (1),O (2):N (1),N (2),N (3),O (1),O (2)]dinickel(II) per­chlorate acetonitrile disolvate

The title complex, [Ni(2)(C(42)H(46)Cl(2)N(6)O(2))(C(2)H(3)O(2))]ClO(4)·2CH(3)CN, was synthesized by condensation of 2,6-diformyl-4-chloro­phenol with N,N-bis­(amino­prop­yl)benzyl­amine in the presence of Ni(II) ions. The ligand is a 28-membered macrocycle with two identical pendant arms. The coordination geometries of the Ni atoms are both octa­hedral. The two Ni atoms are bridged by two phenolate O atoms of the macrocyclic ligand and one acetate ligand, with an Ni⋯Ni distance of 3.147 (4) Å.
