Inside Back Cover: High‐Pressure Synthesis of Metal–Inorganic Frameworks Hf4N20⋅N2, WN8⋅N2, and Os5N28⋅3 N2 with Polymeric Nitrogen Linkers (Angew. Chem. Int. Ed. 26/2020)

Abstract

The metal–inorganic frameworks Hf4N20⋅N2, WN8⋅N2, and Os5N28⋅N2, consisting of transition metals and polymeric nitrogen linkers, were obtained in a one-step synthesis from the elements under high-pressure conditions as described by M. Bykov and co-workers in their Communication on page 10321. The channel-type pores are filled with ordered one-dimensional arrays of nitrogen molecules. Because of the conjugated π-systems in the nitrogen chains, these inorganic polymers are conductive materials.
