Abstract
The crystal structure of the hexavalent neptunium complex NpO2CrO4 · 2[OC(NH2)2] is determined. The crystal data are a = 7.192(2) Å, b = 12.902(4) Å, c = 11.226(3) Å, β = 92.19(2)°, V = 1040.9(4) Å3, space group P21/n, Z = 4, d calcd = 3.223 g/cm3, R = 0.045, and R w = 0.130. The coordination polyhedron of the Np atom is the pentagonal bipyramid whose equatorial plane is formed by the oxygen atoms of the chromate ions and carbamide molecules.
