Abstract in another language

Laser heating of rhenium in a diamond anvil cell to 3000±300 K at about 200 GPa results in formation of two previously unknown rhenium carbides, hexagonal WC-type structured ReC and orthorhombic TiSi2-type structured ReC2. The shortest C–C distances 1.758(3) Å at 219(5) GPa and 1.850(4) Å at 180(7) GPa found in honeycomb-like carbon nets in the structure of ReC2 are quite unusual. The Re–C solid solution formed at multimegabar pressure has the carbon content of ≈ 20 at\%.
