[(1RS,7RS,8RS,14RS)-5,12-Dimethyl-7,14-diphenyl-1,4,8,11-tetraazacyclotetradeca-4,11-diene-⁴N^1,4,8,11]nickel(II) perchlorate

Abstract: The title compound, [Ni(C₂₄H₃₂N₄)](ClO₄), has singlet ground-state nickel(II) complex cations with tetrahedrally twisted [0.013 (4) Å] square-planar coordination by four N atoms of the 14-membered diamine-diimine tetraaza-macrocycle and perchlorate anions. A perchlorate O atom is sited near the tetragonal axis [NiO 2.694 (4) Å], with both N-H groups oriented towards the other side of the plane forming N-HO hydrogen bonds to O atoms of different perchlorate ions, with no O atom near the nickel(II) tetragonal axis.
