摘要：

M(r) = 296.85, orthorhombic, Pnab, a = 6.075 (2), b = 10.366 (2), c = 6.7911 (8) angstrom, V = 427.8 angstrom 3, Z = 4, D(x) = 4.61 g cm-3, lambda(Mo K-alpha) = 0.71069 angstrom, mu = 207 cm-1, F(000) = 540, T = 298 (5) K, R = 0.028 for 642 observed reflections with I > 3-sigma(I). The phase was synthesized hydrothermally at 473 (5) K. The structure consists of strings of edge-sharing CoO6 octahedra running parallel to a, crosslinked by O-Se-O linkages which may be considered to be part of discrete Se2O5(2-) units. The structure is isomorphous with those of ZnSe2O5 and MnSe2O5. Thermogravimetric and X-ray powder diffraction data are also recorded.
