Abstract
N-(Dichlorophosphinoyl)phosphorimidic trichloride, Cl 3 PNP(O)Cl 2 , M r =269.22, monoclinic, P2 1 /c, a=12.573 (5), b=19.183 (4), c=14.985 (4) A, β=110.14 (2) o , V=3393 (1) A 3 , Z=16, D x =2.108 Mg m -3 , λ(Mo Kα)=0.71069 A, μ=2.02 mm -1 , F(000)=2080, T=100 K, R=0.030, wR=0.032 for 4458 unique observed reflections and 325 parameters. There are four molecules in the asymmetric unit. The P-N bonds show a pronounced multiple-bond character, the P-N «double» bonds [1.517 (3)1.530 (3) A] being substantially shorter than the P-N «single» bonds [1.583 (3) 1.593 (3) A], and the P-Cl bonds of the P(O)Cl 2 groups [1.998 (2)2.018 (2) A] are clearly longer than the P-Cl bonds of the NPCl 3 groups [1.956 (2) 1.978 (2) A]
