In the present work, quasi-molecular compounds consisting of one antiproton (p) and one hydrogen-like ion are investigated: He+ - p, Li2+ - p, C5+ - p, S15+ - p, Kr35+ - p, Ho66+ - p, Re74+ - p, U91+ - p. For the calculations, the Dirac equation with two-center potential is solved numerically using the dual-kinetically balanced finite-basis-set method adapted to systems with axial symmetry (A-DKB). Adiabatic potential curves are constructed for the ground state of the above quasi-molecular compounds in the framework of the A-DKB approach. Calculations were also performed for the case of an external magnetic field (the field is taken into account non-perturbatively). Zeeman shifts of the quasi-molecular terms are obtained for a homogeneous magnetic field with a strength of the laboratory order (up to 100 Tesla) directed along the axis of the molecule.
