New shell model Hamiltonians are derived for the T=1 part of the residual interaction in the f5∕2  p3∕2  p1∕2  g9∕2 model space based on the analysis and fit of the available experimental data for 2857Ni29–2878Ni50 isotopes and 2977Cu50–50100Sn50 isotones. The fit procedure, properties of the determined effective interaction as well as new results for valence-mirror symmetry and seniority isomers for nuclei near 78Ni and 100Sn are discussed.
