Explored compositions, generated by substituting the apical oxygens and rare earth ion in La$_2$CuO$_4$ to form he $R_2$CuO$_2$S$_2$ series. the family of compounds $R_2$CuO$_2$S$_2$.  Plotted are the extracted charge-transfer energy vs. the apical distance of sulfur atom after structural relaxation in LDA.
