Silver(I) salts with penicillin anions

Аннотация

Silver(I) salts with benzylpenicillin (Bzp^–), ampicillin (Amp^–), and oxacillin (Oxa^–) anions with compositions of AgBzp, AgAmp, and AgOxa are isolated from an aqueous solution in the solid state and characterized by IR spectroscopy and thermal analysis (TG/DSC). IR spectroscopy data lead to the conclusion that Ag(I) coordinates the Oxa^– ion through carbonyl oxygen atoms of the ß-lactam and amide groups. No coordination is observed for the Bzp^– and Amp^– anions.
