Abstract - Summary
(short description): | |
| Single crystals of [(UO2)(SeO4)(H2SeO3)][(SeO4)(C3H8N6)] (1) were prepared by evaporation from 2 ml aqueous solution of uranyl nitrate, melamine and selenic acid. The unit cell parameters were determined by the least squares method. Compound (1) has a monoclinic symmetry, space group P21/c, a = 16.247(4) Å, b = 8.680(2) Å, c = 13.347(3)Å, = 90.615(5) o, V = 1882.1(8) Å3. The crystal structure was solved by direct methods from X-ray diffraction data and refined by the least-squares method to R1 = 0.0317 (wR2 = 0.0388) for 4068 reflections with |Fo| ≥ 4σF. |
