The Pd(II) atom in the title compound, [Pd(C24H49P2)Cl], has a distorted square-planar CClP2 coordination geometry with the P,C,P'-tridentate ligand forming two five-membered metallacycles. The cyclo-hexane ring is aligned with the Pd(II) coordination plane due to C-H activation in an equatorial position, giving a tri-equatorial conformation of the cyclo-hexyl ring.

In the title compound, [Ni(C24H36P3)Cl], the Ni(II) atom adopts a distorted square-planar geometry with the two neutral P atoms of the tridentate ligand trans to one another. Bond lengths and angles of the phosphide P atom feature a pyramidal geometry of the donor atom, which forms a single bond with the Ni(II) atom, retaining a stereochemically active lone pair.

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 82.1...
