Intensive and extensive searches for superconductivity in materials iso-structural, iso-electronic and iso-valent with magnesium diboride, MgB2, have not produced superconductors with Tc close to 39K. Recently, we proposed lithium magnesium nitride, LiMgN, as a potential MgB2-like superconductor, based on symmetry considerations of averages of electronegativity, valence electrons, atomic number and formula weight. Our studies show that there are other materials that meet the same symmetry considerations like LiMgN. Here we propose that magnesium beryllium carbide, MgBeC, one of such materials, should be a superconductor like MgB2, with Tc near 39K.
