The results of experimental investigations and theoretical calculations of electronic characteristics of zirconium dode-caboride single crystals are presented. As demonstrated, ZrB12 belongs to the class of partially covalent compounds of tran-sition metals having light elements, in which directed cova-lent bonds of boron form high mechanical strength, whereas their metallic and, hence, superconducting properties are formed by zirconium d-states hybridizing with external 2p-states of boron.
