In the title compound, [NiBr(2)(C(31)H(32)NP)], (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) degrees compensated by the Br-Ni-Br angle of 126.385 (18) degrees. 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. |
