請(qǐng)問高氯酸根的無序問題怎么解決?
|
| 我的單晶質(zhì)量不是很好,但是感覺數(shù)據(jù)也能接受,里邊的高氯酸根有無序問題,check后居然是ClO5,還有一個(gè)溶劑分子很能確定,請(qǐng)高手支招,幫忙,急用數(shù)據(jù)。。 |

五種高氯酸無序 類型1 One of the two perchlorates was found to be disordered: a model in which one oxygen atom islocated on an apex while two sets of three oxygen atoms are disordered and located along the chlorine and apex oxygen. 類型2 The cations lie onmirror planes, as do the perchlorate anions, one of which is disordered (modeled as 45 : 5% over two sites on the mirror plane), and the uncoordinated ethanol solvate molecules. 類型3 The uncoordinated perchloratewasmodelled as rotationally disordered about oneCl–Obond, the other three oxygen atom site occupancies refining to 0.753(9) and complement. 類型4 There is one disordered perchlorate anion in 1. The O(7), O(8) and O(9) oxygen atoms, bonded to Cl(2), were each split into two fragments (O(7)/O(7’), O(8)/O(8’), O(9)/O(9’)) and were refined. This refinement led to a 0.87 : 0.13 ratio in occupancy over two positions for O(7) and O(8) and a 0.60 : 0.40 ratio in occupancy over two positions for O(9). The O(10) atom was split into three fragments (O(10)/O(10’)/O(10’’)), with refinement leading to a 0.55 : 0.27 : 0.18 ratio in occupancy over three positions. 類型5 For 3, one perchlorate moiety is grossly disordered about a position of 3(-)(S6) point symmetry and was modelled as a single molecule with a tightly restrained geometry and site occupancies suitable to sum to one molecule in total. |
