The title complex prepared through an electrophilic substitution of (11,13-diemthyl-1,4,7,10-tetraaza-10,12-cyclotridecadienato)nickel(II) bromide with <I>p</I>-methylbenzoyl chloride was subjected to single-crystal X-ray diffraction analysis. The analysis has revealed completion of the substitution reaction, pseudo C<SUB>2</SUB> symmetry of the macrocyclic complex minus the substituent, and an essentially square planar coordination environment with slight tetrahedral distortion. The substituted <I>p</I>-methylbenzoyl group is tilted with respect to the least-squares plane of the conjugated six-membered chelate ring, where the dihedral angle between them is 69.2°.
