## Abstract In the natrochalcite-type compounds NaCu~2~(H~3~O~2~)(SO~4~)~2~ and RbCu~2~(H~3~O~2~)(SeO~4~)~2~ the lengths of the two different hydrogen bridges vary widely: 2.44 ร and 2.70 ร in the Na-S member, and 2.60 ร and 3.03 ร in the Rb-Se member. Both structures were refined by single-crystal
