<i>X-Seed 4</i>: updates to a program for small-molecule supramolecular crystallography
Leonard J. Barbour
Abstract
X-Seed is a native Microsoft Windows program with three primary functions: (i) to serve as a graphical user interface to the SHELX suite of programs, (ii) to facilitate exploration of crystal packing and intermolecular interactions, and (iii) to generate high-quality molecular graphics artwork suitable for publication and presentation. Development of X-Seed Version 1.0 began in 1998, when point-and-click crystallographic software was still limited in scope and power. Considerable enhancements have been implemented within X-Seed over the past two decades. Of particular importance are support for the SHELX2019 programs ( SHELXS , SHELXD , SHELXT and SHELXL ) for structure solution and refinement, and MSRoll for rendering void spaces in crystal structures. The current version ( i.e. Version 4) of X-Seed has a new interface designed to be more interactive and user friendly, and the software can be downloaded and used free of charge.
