Mass-dependencies of a number of bound state properties are investigated insome light two-electron exitonic complexes (or clusters) $Z^{+} e^{-} e^{-}$,where $m_e \le m_Z \le 2 m_e$. These exitonic complexes (or model ions) play agreat role in modern solid state physics, since such complexes describe opticalabsorption in a number of semiconductors. We also derived and tested a numberof accurate mass-interpolation formulas for these properties. In general, ourmass-interpolation formulas allow one to predict (fast and accurately)numerical values of these bound state properties in the `new' exitoniccomplexes, i.e., in three-body exitonic complexes with new mass ratios.
