In the title tris-(pyrazol-yl)borate (Tp(Ph2)) complex, [NiBr(C(45)H(34)BN(6))], the Ni, Br and B atoms lie on a crystallographic threefold axis and a distorted NiN(3)Br tetra-hedral geometry arises for the metal ion. In the crystal, C-H⋯(C=C) and C-H⋯π inter-actions help to establish the polar crystal packing.
