Average selection

The Average section has its own element/atom selection. Standard deviations describe the scatter of grouped values.

Average bond lengths / distances

Average bond angles

Coordination selection

Ligand atoms are taken from the CIF geometry bond table. Adjust the ligand selection manually if disorder, alternative positions, or unwanted contacts are present.

Ligand atoms from CIF geometry bond table

Calculated geometry parameters

CShM values are calculated for coordination numbers 2–6 and are shown as a comparison between the available ideal shapes for the current coordination number. Descriptors include τ₄, τ₄′, τ₅, and coordination polyhedron volume.

Single distance

Resulting operation
Distance with estimated e.s.d. not available

The e.s.d. for calculated distances is estimated from coordinate and unit-cell e.s.d.s. Correlations are not considered.

Search distance range

Search results are added directly to the table below. Use the Add checkbox there to include or exclude them.

Added interatomic distances

Checked entries are included in preview, export, and average calculations.

Disorder Helper

Disorder information is extracted from atom-site disorder fields and, if available, from the embedded SHELXL RES file. Moiety and Comment fields can be edited manually.

No CIF loaded.

Disorder table

The Moiety field supports free text and suggestions from the moiety library. Comments are pre-filled where possible and can be edited.

SVG output

Drag the SVG to rotate the view. Double-click to reset the view. Shift-click an atom toggles its label. Ctrl-click or Cmd-click an atom, bond, or hydrogen bond hides/removes it. Shift+Ctrl-click or Shift+Cmd-click an atom shows attached coordinate H atoms.
