A detailed study of the solution chemistry and mass spectrometry of six carboxylato‐organogermanium compounds in aqueous solution has been carried out using electrospray ionization and MS n techniques. The different types of hydrolysis products and their probable structures, which include the oligomers and their fragment ions plus water adduct ions formed by ion‐molecule reactions, are presented, e.g., HO‐cyclic‐(‐Ge(O − )CH 2 CH 2 COO) A, HO‐cyclic‐(‐Ge(O‐cyclic‐(Ge(O − )CH 2 CH 2 COO)CH 2 CH 2 COO) B, − OGeO‐cyclic‐(‐Ge(OH)CH 2 CH 2 COO) C, and − CH=CHGeO‐cyclic‐(‐Ge(OH)CH 2 CH 2 COO) D, etc. The proposed cyclic structures are confirmed by theoretical calculations.
