摘要：
The reaction between PuO2 and SeO2 under mild hydrothermal conditions results in the formation of Pu(SeO3)(2) as brick-red prisms. This compound adopts the Ce(SeO3)(2) structure type, and consists of one-dimensional chains of edge-sharing [PuO8] distorted bicapped trigonal prisms linked by (SeO3) units into a three-dimensional network. Crystallographic data: Pu(SeO3)(2), monoclinic, space group P2(1)/n, a = 6.960(1)angstrom, b = 10.547(2)angstrom, c = 7.245(1)angstrom, beta = 106.880(9)degrees, V = 508.98(17) angstrom(3), Z = 4 (T = 193 K), R(F) = 2.92% for 83 parameters with 1140 reflections with 1>2 sigma(I). Magnetic susceptibility data for Pu(SeO3)(2) are linear from 35 to 320K and yield an effective moment of 2.71(5)mu(B) and a Weiss constant of -500(5) K. (C) 2008 Elsevier Inc. All rights reserved.
