摘要:
A study of Cu-O vibration frequencies in 32 isostructural mixed copper complexes containing eight differently substituted phenanthrolines and four different oxygen donor bidentate ligands, is presented. In all cases linear correlation was found between phenanthroline pK(a) values and the studied vibration frequencies, suggesting that an increase in phenanthroline basicity weakens Cu-O bonds in this type of compound.
