Abstract
An analysis is presented for the results obtained in the studies initiated by A. E. Shvelashivili, Corresponding Member, Academy of Sciences of Georgia, and continued by us after he has passed away. The studies are focused on guanidinium and citrate ion containing compounds. It is found that protonation delocalizes the π bond and equalizes the С-N bonds in the guanidine grouping and that the doubly or triply deprotonated citric acid anion in complex compounds acts both as a bi- and tridentate ring-forming ligand.
