Preparation and Single-Crystal Characterization of <i>ⁱ</i>Pr₂P(S)NHP(S)<i>ⁱ</i>Pr₂ and Homoleptic [<i>ⁱ</i>Pr₂P(S)NP(S)<i>ⁱ</i>Pr₂]^- Complexes of Zinc, Cadmium, and Nickel

Abstract

The X-ray structure of iPr2P(S)NHP(S)iPr2 reveals that the sulfur atoms adopt a gauche conformation. The tetrahedral complexes of Zn, Cd, and Ni contain puckered boatlike MS2P2N rings with enlarged P−N−P angles compared to the starting material.
