求解晶體解析中的問題
|
|
測了個晶體,出現(xiàn)了好幾個錯誤,我也不懂晶體精修方面的知識,那位大俠幫幫忙解決一下,感激不盡!。 這是check CIF的結(jié)果: Alert level A DENSX01_ALERT_1_A The ratio of the calculated to measured crystal density lies outside the range 0.80 <> 1.20 Calculated density = 1.977 Measured density = 0.000 SYMMG02_ALERT_1_A The _symmetry_equiv_pos_as_xyz values are inconsistent with the H-M symbol given From the CIF: _symmetry_equiv_pos_as_xyz x, y, z -x, y, -z+1/2 -x, -y, -z x, -y, z-1/2 These symops generate the Hall space group symbol -p_2yc From the CIF: _symmetry_space_group_name_H-M p-1 From the xyz: _symmetry_space_group_name_H-M p_1_2/c_1 ALERT 4 symops in cif, 2 symops generated ________________________________________ Alert level B SYMMS02_ALERT_1_B No unit-cell angle should be equal to 90 for a triclinic cell Cell 14.8138 6.4171 7.0081 Angles 90.0000 90.7950 90.0000 PLAT057_ALERT_3_B Correction for Absorption Required RT(exp) ... 1.25 PLAT093_ALERT_1_B No su's on H-atoms, but refinement reported as . mixed ________________________________________ Alert level C ABSTY03_ALERT_1_C The _exptl_absorpt_correction_type has been given as none. However values have been given for Tmin and Tmax. Remove these if an absorption correction has not been applied.
