In the title complex, [Ni(C(30)H(23)O(2)P(2))I], the divalent Ni atom is coordinated by two P atoms and one C atom from the 1,3-bis-[(diphenyl-phosphan-yl)-oxy]benzene ligand; the distorted square-planar geometry is completed by an iodide ligand. The largest distortions from ideal square-planar geometry are reflected in the P-Ni-P angle of 164.20 (2)° and the P-Ni-C angles of 82.09 (6) and 82.11 (6)°. The rather short Ni-C bond length [1.890 (2) Å] is anti-cipated in light of the much stronger trans influence of the aryl moiety compared to the iodide ligand. The P-bound phenyl rings adopt different orientations to minimize steric repulsion among themselves.
