摘要
列举16 例按P1 解出的晶体结构,其空间群应描述为单斜晶系的C2/c,并讨论从P1 修正为三方的R3 和四方的I41/a 的晶体结构各1 例。分析揭示判断失误的线索。最后强调在结构报告中完整发表原子坐标数据的重要意义。
We present 16 structures that were original described as \$P\$1 but are properly described as monoclinic \$C2/c,\$ and one revised from \$P\$1 to triganal \$R\$3 as well as the other one from P 1 to tetragonal I4\-1/a. The clues for correction of symmetry are analysed, and the great importance of publishing the full atomic coordinates in a structural report is emphasized.\;
