We report the crystal structure evolution of CaCu_{0.2}Mn_{6.8}O_{12} as a function of temperature between 10 K and 290 K. The analysis of the diffraction data is carried out with the Rietveld method applied to the average trigonal structure of CaCu_{0.2}Mn_{6.8}O_{12}. The x = 0.2 member shows similar low temperature extrema for the unit cell parameter evolution as the previously reported x = 0.1 and x = 0 members of the CaCu_xMn_{7-x}O_{12} system. All magnetic and crystallographic transition temperatures indicated by the unit cell parameter evolution obtained by powder X-ray diffraction methods systematically decrease with increasing Cu content, x.
