文摘

Single crystals of dimorphic Cu5(SeO3)4Br2 were prepared by chemical vapor transport reactions. Both of compounds are the first copper selenite-bromides. Solid-state exchange reactions yielded a new compound Na2[Cu7O2](SeO3)4Br4. Structures of new compounds contain channels occupied by Br− ions and lone pairs on Se4+.
