The program KPLOT was written by Rudolf Hundt (1941 - 2020) at the Institute for Inorganic Chemistry, University of Bonn, Germany and is designed to draw and analyze crystal structures. Starting from the first version in 1979 the software has been continuously improved and updated. It provides:

  • Various strategies for step-wise building up crystal structure models
  • Facility to work with two crystal structures at the same time
  • Tools for the comparison of two crystal structures
  • Plotting of ball-and-stick models, thermal ellipsoids and coordination polyhedra
  • Symmetry analysis and transformation, space group determination
  • Calculation of interatomic distances, angles and torsion angles


You can download the manual as well as a brief version history. A tutorial as well as a comprehensive reference manual (both as PDF-files) are contained in the download archives below.
