Type: article

Abstract: The crystal structures of 5-cyclohexyl-1,3-diphenyl-1,3,5-diazaphosphinane, C 21 H 27 N 2 P, and its oxidized phosphine oxide, 5-cyclohexyl-1,3-diphenyl-1,3,5-diazaphosphinan-5-one, C 21 H 27 N 2 OP, have primitive monoclinic symmetry (both in space group P 2 1 /m) at 150 K. The nickel(II) complex trans -dichloridobis(5-cyclohexyl-1,3-diphenyl-1,3,5-diazaphosphinane-κ P )nickel(II), [NiCl 2 (C 21 H 27 N 2 P) 2 ], consists of two diazaphosphinane ligands (monoclinic C 2/ c , 150 K) bound through their phosphorous atoms, which adopts a four-coordinate square-planar geometry. The bulky cyclohexyl substituents of the ligand are axially positioned in their respective chair six-membered ligand rings, and are in an anti -configuration, with respect to the square plane. The nickel atom is located on a center of symmetry.
