In the framework of potential models for heavy quarkonium the mass spectrum for the system ([ital [bar b]c]) is considered. Spin-dependent splittings taking into account a change of a constant for the effective Coulomb interaction between the quarks, and widths of radiative transitions between the ([ital [bar b]c]) levels are calculated. In the framework of QCD sum rules, the masses of the lightest vector [ital B][sub [ital c]][sup *] and pseudoscalar [ital B][sub [ital c]] states are estimated, the scaling relation for leptonic constants of heavy quarkonia is derived, and the leptonic constant [ital f][sub [ital B][ital c]] is evaluated.
