Abstract

We propose a new structure, namely Mg₂BC₃, which consists of BC₃ honeycomb layers intercalated with magnesium atoms. Energy minization is obtained for a relatively large distance between the BC₃ layers (c = 0.53 nm). Band structure calculations show an unusually large metallic density of states at the Fermi level, much higher than that in MgB₂. The similarity of the proposed layered Mg₂BC₃ structure to that of MgB₂ suggests that Mg₂BC₃ may be a superconductor with a relatively high temperature.
