High‐Pressure Synthesis of Metal–Inorganic Frameworks Hf 4 N 20 ⋅N 2 , WN 8 ⋅N 2 , and Os 5 N 28 ⋅3 N 2 with Polymeric Nitrogen Linkers

Polynitrides are intrinsically thermodynamically unstable at ambient conditions and require peculiar synthetic approaches. Now, a one-step synthesis of metal-inorganic frameworks Hf4N20 center dot ...
