CIF2SX: A CIF to SHELXL converter

Program CIF2SX will take as input a legal CIF file and output a legal SHELXL93 instruction file. A SHELX file for each data_ block may be obtained.

The following information in the CIF is required:

unit cell parameters and wavelength: if latter is missing MoKalpha is assumed.
chemical formula: preferably as sum or structural rather than moieties (interpretation of latter may not be succesful)
number of formula units per cell.
elemental types: as atom_type_symbol and atom_site_type_symbol
atomic positional, occupation (default 1.), thermal parameters
space group symbol: either H-M or Hall
equivalent positions: as xyz

If any of the above data items are missing the program will halt.

In addition, the CIF dictionary CIFDIC.C91 should be present in the specified directory "cif$dir" if data items are to be checked.

NB. This program also produces files suitable for SHELX97

The program is supplied in a ZIP file cif2sx.zip containing:

This utility was written by Louis Farrugia at the University of Glasgow. See also his extremely useful Windows 95/NT ports of ORTEP3 and PLATON97.
