Compounds containing planar boron sheets are of current interest because of the important role of such sheets in the superconducting behavior of MgB2. Among them, solid state ternary borides of stoichiometry REMB4 such as YCrB4 (RE = rare earth metal and M = transition metal or heavy main group atom) exhibit infinite two-dimensional layers of boron atoms with topologies different from that encountered in MgB2. Parameters such as the symmetry, the electron count and the nature of the RE and M elements will be analyzed with the aid of density-functional band structure calculations to address the issues of structural arrangement and some physical properties, in particular thermoelectrical properties.
