Abstract
Two new complex Np(VI) nitrates with carbamoylurea (biuret) and with a derivative of terpyridine (Ph-Terpy) of the composition [(NpO2)(biuret)(NO3)2] (I) and [H2(Ph-terpy)(NO3)]2[NpO2(NO3)4] (II) have been synthesized and structurally characterized. The coordination environment of Np atoms in compounds are distorted hexagonal bipyramids with “yl” oxygen atoms in apical positions. The equatorial plane of the bipyramid in complex I is formed by oxygen atoms of two bidentate NO3– anions and an electroneutral ligand. The equatorial plane of the bipyramid in II is formed by oxygen atoms of two bidentate and two monodentate NO3– anions. The twice protonated Ph-terpy is the basis of the complex cation [H2(Ph-terpy)(NO3)]+.
