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.
