PLAT701 Type_1 Test for consistency of Bonds and Coordinates in CIF

Bond distances given in the CIF are cross-checked with corresponding values calculated from the coordinates. Alerts are set at 1,2 and 3 sigma deviation levels.

Note: Default s.u.'s are used where no s.u. given (e.g. for C-H) In general, all differences should be within the associated s.u. Small differences may arise from rounding. Very large deviation (or zero distance) normally indicate incorrectly specified symmetry operations on the associated atoms, or 'cut-and-pasting' of incompatible CIF's.

例:PLAT701_ALERT_1_A Bond Calc 1.52(3), Rep 1.39(2), Dev.. 4.33 Sigma

C26A -C80A 1.555 1.555 ........ # 77 Check

解决策略:几个的话可以删掉,如果很多的话,说明结构解析有问题。

PLAT702 Type_1 Test for consistency of Angles and Coordinates in CIF

Bond Angles given in the CIF are cross-checked with corresponding values calculated from the coordinates. Alerts are set at 1,2 and 3 sigma deviation levels. In general, all differences should be within the associated s.u. Small differences may arise from rounding. Very large deviations normally indicate incorrectly specified symmetry operations on the associated atoms, or 'cut-and-pasting' of incompatible CIF's.

PLAT703 Type_1 Test for consistency of Torsions and Coordinates in CIF

Torsion angles given in the CIF are cross-checked with corresponding values calculated from the coordinates. Alerts are set at 1,2 and 3 sigma deviation levels. In general, all differences should be within the associated s.u. Small differences may arise from rounding. Very large deviations normally indicate incorrectly specified symmetry operations on the associated atoms, or 'cut-and-pasting' of incompatible CIF's.

PLAT704 Type_1 Test for consistency of Contact Distances and Coordinates in CIF

Intermolecular contacts listed in the CIF are checked against the coordinates in the CIF. Alerts are set at 1,2 and 3 sigma deviation levels.

警告原因:氢键中键长键角大小错误。

解决策略:修改ins中HTAB命令,重新生成CIF文件。

PLAT705 Type_1 Test for consistency of H-Bond D-H distances and Coordinates in CIF

Hydrogen-Bond D-H listed in the CIF is checked. Alerts are set at 1,2 and 3 sigma deviation levels.

警告原因:氢键中键长键角大小错误。

解决策略:修改ins中HTAB命令,重新生成CIF文件。

PLAT706 Type_1 Test for consistency of H-Bond H..A Distances and Coordinates in CIF

Hydrogen-Bond H..A listed in the CIF is checked. Alerts are set at 1,2 and 3 sigma deviation levels. This ALERT is generally related to incorrect symmetry codes. The symmetry number s in the symmetry code s_pqr should correspond to the expression for s in the CIF. Those expressions can be different for different software packages. E.g. pasting H-bond table data generated with PLATON into a CIF generated with SHELXL may raise this ALERT. Manual correction of the symmetry code should be trivial.
