# XYZ format

## XYZ format

Marvin imports and exports XYZ molecule files that have the following format:

[ # optional comment line ]     not written but allowed at import
[  N                      ]     always written, but can be omitted in imported files
[  name\tE                ]     always written, but can be omitted in imported files
atom1 x y z
atom2 x y z
...
atomN x y z

where N is the number of atoms and E is the energy (optional). If energy is set for the molecule, then it is separated from the molecule name with a TAB ("\t") character.

Restrictions of the XYZ format:

Code: xyz

Do not export 2D drawings in XYZ!

XYZ export in Marvin is only meaningful for 3D molecules with realistic atomic distances.
