In the title compound, [Ni(C45H34BN6)(C10H9N3)]Br·CH2Cl2, the NiII atom is five-coordinated by the tridentate hydro­tris­(3,5-diphenyl­pyrazol­yl)borate ligand and a bidentate di-2-pyridyl­amine ligand in a distorted square-pyramidal geometry. In the crystal, inter­molecular N—H⋯Br and C—H⋯Br hydrogen bonds link the Ni complex cations and the Br− ions, forming a chain along the c axis.
