WebAll chiral crystal structures belong to the Sohncke space groups, which contain only symmetry elements of the first kind, i.e., rota-tions, rototranslations, and translations, but no inversion centers, rotoinversion axes, or mirror planes, e.g., symmetry elements of the second kind (1, 2). Among the Sohncke groups, there are 11 pairs of WebTwo phenanthroline–manganese inclusion complexes with [MnCl(H2O)(phen)2]+ core were prepared in the presence of dicarboxylic acid and their structures were determined.
