The structure of Tetraphenyl Imidodiphosphate, C₂₄H₂₁NO₆P₂

Abstract

Abstract M r = 481.24, monoclinic, P 2 1 /c, a = 12.009(3), b = 12.305(5), c = 18.993(7) Å, β = = 122.1(1) 0 , V = 2377.2(6) Å 3 , D x = 1.349 Mgm −3 , Z = 4. Final R = 0.051 for 2690 independent reflections excluding those with | F 0 | < 4 σ( F 0 ). Intensities were measured with an automatic diffractometer. The two phosphoryl oxygen atoms are in trans position. The acidic hydrogen atom is bonded at the nittogen atom. The molecules form dimers connected by NH … O intermolecular hydrogen bonds. Results are compared with those of the structure of tris(tetraphenylimidodiphosphato)ytterbium (III).
