Crystal structure of (2-{[(8-aminona­phthalen-1-yl)imino]­meth­yl}-4,6-di-tert-butyl­phenolato-κ(3) N,N′,O)bromido­nickel(II)

The title compound, [NiBr(C(25)H(29)N(2)O)], contains an Ni(II) atom with a slightly distorted square-planar coordination environment defined by one O and two N atoms from the 2-{[(8-aminona­phthalen-1-yl)imino]­meth­yl}-4,6-di-tert-butyl­phenolate ligand and a bromide anion. The Ni—O and Ni—N bond lengths are slightly longer than those observed in the phenyl backbone counterpart, which can be attributed to the larger steric hindrance of the naphthyl group in the structure of the title compound. The mol­ecule as a whole is substanti­ally distorted, with both the planar naphthalene-1,8-di­amine and imino–meth­yl–phenolate substitutents rotated against the NiN(2)OBr plane by 38.92 (7) and 37.22 (8)°, respectively, giving the mol­ecule a twisted appearance. N—H⋯Br hydrogen bonds and N—H⋯C(π) contacts connect the mol­ecules into dimers, and additional C—H⋯Br contacts, C—H⋯π inter­actions, and an offset stacking inter­action between naphthyl units inter­connect these dimers into a three-dimensional network.
