The 1:1 Antimony Trichloride Adduct of Chlorobis(2,6-dimethylpiperidin-1-yl)phosphine Oxide

In the structure of the title complex, [(C₇H₁₄N)₂ClP(O)].SbCl₃, shows a distorted trigonal bipyramidal geometry (including the lone pair). The O—Sb interaction of antimony with the phosphoryl O atom is only moderate and is weaker than that observed in the known compound Cl₃PO→SbCl₅.
