Discovery of the Last Remaining Binary Platinum-Group Pernitride RuN2
The last remaining marcasite‐type RuN2 was successfully synthesized by direct chemical reaction between ruthenium and molecular nitrogen above the pressure of 32 GPa. For the first time, we found that Ru 4d is weakly hybridized with N 2p in the structure by using transmission electron microscopy equ...

| description | The last remaining marcasite‐type RuN2 was successfully synthesized by direct chemical reaction between ruthenium and molecular nitrogen above the pressure of 32 GPa. For the first time, we found that Ru 4d is weakly hybridized with N 2p in the structure by using transmission electron microscopy equipped with electron‐energy‐loss spectroscopy. Our finding give important knowledge about the platinum‐group pernitride with respect to the chemical bonding between platinum‐group element and nitrogen.
The last remaining binary platinum‐group pernitride RuN2 was successfully synthesized by direct chemical reaction between ruthenium and molecular nitrogen above the pressure of 32 GPa. RuN2 crystallizes with the marcasite‐type structure, as do OsN2 and RhN2. The zero‐pressure bulk modulus was experimentally determined to be 330(5) GPa. TEM electron‐energy‐loss spectroscopy (EELS) analyses on the marcasite‐type RuN2 revealed that Ru 4d is weakly hybridized with N 2p (see figure). |
