Bis{N-[bis-(pyrrolidin-1-yl)phosphor-yl]-2,2,2-trichloro-acetamide}di-nitrato-dioxidouranium(VI)
Abstract:
The crystal structure of the title compound, [U(NO(3))(2)O(2)(C(10)H(17)Cl(3)N(3)O(2)P)(2)], is composed of centrosymmetric [UO(2)(L)(2)(NO(3))(2)] mol-ecules {L is N-[bis-(pyrrolidin-1-yl)phosphor-yl]-2,2,2-trichloro-acetamide, C(10)H(17)Cl(3)N(3)O(2)P}. The U(VI) ion, located on an inversion center, is eight-coordinated with axial oxido ligands and six equatorial oxygen atoms of the phosphoryl and nitrate groups in a slightly distorted hexa-gonal-bipyramidal geometry. One of the pyrrolidine fragments in the ligand is disordered over two conformation (occupancy ratio 0.58:0.42). Intra-molecular N-H⋯O hydrogen bonds between the amine and nitrate groups are found.

1° Amines to Diazonium or Aryldiazonium Salts: Diazotization with NaNO2 Overview
The nitrous acid is unstable. Hence, it is formed in situ from a solution of sodium nitrite and cold aqueous acids such as hydrochloric or sulfuric acid. In an acidic solution, the –OH group of nitrous acid undergoes protonation to give oxonium ion, followed by water loss...
