Abstract
Subject headings
Close
- The elements hydrogen, carbon, and nitrogen are among the most abundant in the solar system. Still, little is known about the ternary compounds these elements can form under the high-pressure and high-temperature conditions found in the outer planets' interiors. These materials are also of significant research interest since they are predicted to feature many desirable properties such as high thermal conductivity and hardness due to strong covalent bonding networks. In this study, the high-pressure high-temperature reaction behavior of malononitrile H2C(CN)(2), dicyandiamide (H2N)(2)C=NCN, and melamine (C3N3)(NH2)(3) was investigated in laser-heated diamond anvil cells. Two previously unknown compounds, namely alpha-C(NH)(2) and beta-C(NH)(2), have been synthesized and found to have fully sp(3)-hybridized carbon atoms. alpha-C(NH)(2) crystallizes in a distorted beta-cristobalite structure, while beta-C(NH)(2) is built from previously unknown imide-bridged 2,4,6,8,9,10-hexaazaadamantane units, which form two independent interpenetrating diamond-like networks. Their stability domains and compressibility were studied, for which supporting density functional theory calculations were performed.
