摘要
The crystal structure of the [NpO2(NO3)(Terpy)(H2O)] complex between pentavalent neptunium and 2,2',6',2"-terpyridine is determined. The crystal data are as follows: a = 11.130(3) Angstrom, b = 7.916(2) Angstrom, c = 18.324(5) Angstrom, beta = 100.873(6)degrees, V = 1585.5(8) Angstrom(3), Z = 4, space group is P2(1)/n, R = 0.044, and wR(F-2) = 0.092. The coordination polyhedron of the Np atom is a pentagonal bipyramid whose equatorial plane includes three nitrogen atoms of the Terpy molecule and two oxygen atoms of the nitrate ion and the water molecule.
