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 P21/n, a 6.960(1) A , b 10.547(2) A , c 7.245(1) A , b 106.880(9)1, V 508.98(17) A 3, Z 4 (T 193 K), R(F) 2.92% for 83 parameters with 1140 re ections with I42s(I). Magnetic susceptibility data for Pu(SeO3)2 are linear from 35 to 320 K and yield an effective moment of 2.71(5) mB and a Weiss constant of -500(5) K.
