We have investigated the electronic structures of hydro-boron−carbon compounds by first principles calculations. We predict that hydro-boron−carbon compounds have stable semiconducting and metallic conformations. During step by step hydrogenation, semiconductor−semiconductor−metal transitions appear in the hydro-BC3 compounds and metal−semiconductor−metal transitions appear in the hydro-BC5 and hydro-BC7 compounds. We find that the bonding status of the boron pz orbitals play an important role in tuning the electronic properties of hydro-boron−carbon compounds.
