Abstract
The structures of two predominantly potassium members of the labuntsov ite-nenadkevichite family are refined to R = 0.036 and 0.058 for 1085 and 1318 unique reflections, respectively. The compositions and occupa ncies of the mixed-atom sites in the octahedral columns and the interc olumn spaces are determined. The hydrogen atoms of water molecules are located. The structural and spectral features of the minerals studied are compared with those of other members of this family.
