摘要

Syntheses within the system CuO-SeO2-H2O revealed four copper(II)-oxo-selenites. The crystal structures of these compounds were determined by single crystal X-ray techniques. Chemical formulae, lattice parameters and space groups are: Cu2O(SeO3)-I a=8.925 (1) Å, P213, Cu2O(SeO3)-II a=6.987 (5) Å,b=5.953 (4) Å,c=8.429 (6) Å, β=92.17 (3)°, P21/n, Cu4O(SeO3)3-I a=15.990 (8) Å,b=13.518 (8) Å,c=17.745 (12) Å, β=90.49 (5)°, P21/a, and Cu4O(SeO3)3-II a=7.992 (6) Å,b=8.141 (6) Å,c=8.391 (6) Å, α=77.34 (3)°, β=65.56 (3)°, γ=81.36
