A pillar-layered chalcogenide framework assembled by [Mn5S12N12]n layers and [Sb2S5] inorganic pillars.

Reported here is an attractive pillar-layered metal chalcogenide open framework, in which [Sb2S5] building units act as pillars between [Mn5S12(N2H4)6]n layers. The obtained compound exhibits high stability in both acid and base media and good performance in the electrocatalytic oxygen reduction reaction (ORR).
