In the title compound, [NiBr2(C31H32NP)], (I), the second reported example of a nickel–iminophosphine N,P‐chelate in which the Ni atom has tetrahedral coordination, the Ni coordination is distorted as a consequence of the N—Ni—P chelate bite angle of 91.07 (6)° compensated by the Br—Ni—Br angle of 126.385 (18)°. In (I) and its analogue, viz.dichloro{[2‐(4‐isobutyloxazol‐2‐yl)phenyl]diphenylphosphine‐N,P}nickel(II), the Ni—N and Ni—P distances are greater and the N—Ni—P ligand bite angles smaller than those observed in a series of related complexes with square‐planar nickel. |
