一個晶體中有兩個相同的不對稱單元的結構,如何將其轉化成只有一個不對稱單元的結構 已有2人參與
|
| 有一個晶體數據,投稿時,晶胞是13.339 14.176 15.387 108.73 90.04 105.24 V=2647,晶體中有兩個相同的不對稱單元,而審稿人要求用另外一個晶胞去解:9.694 11.992 12.812 110.38 94.93 104.92 V=1323,晶體應該是只有一個不對稱單元(系列同構的稀土化合物)。請各位大神指點如何操作,才能轉化晶胞。謝謝! |

審稿人的意見: 3.1 There has been a problem with the correct determination of the unit-cell data for this complex. Routine checks show that the reported triclinic cell data with Z = 2 can be transformed to a new smaller triclinic cell which is now really isomorphous with that reported for compound 2, with Z = 1.
