| Abstract: | The characteristics of nonphonon pairing of hybridized p and d electrons in planar complexes RuO2 are studied in the presence of a strong short-range Hubbard repulsion. The phase diagram of superconductivity as a function
of the degree of underfilling of the 2p
6 and 4d
6 shells in the RuO2 complexes is calculated in a generalized Hubbard model.
