L-Cysteinium⋯L-Cysteine Phosphite

In the system L-cysteine-H 3 PO 3 –H 2 O, a new salt with a dimeric cation, (L-CysH⋯L-Cys)(H 2 PO 3 ), has been obtained. The compound exhibits incongruent solubility and is synthesized using an equimolar ratio of L-cysteine and phosphorous acid. It crystallizes in the orthorhombic space group P 2 1...

Zusammenfassung:In the system L-cysteine-H 3 PO 3 –H 2 O, a new salt with a dimeric cation, (L-CysH⋯L-Cys)(H 2 PO 3 ), has been obtained. The compound exhibits incongruent solubility and is synthesized using an equimolar ratio of L-cysteine and phosphorous acid. It crystallizes in the orthorhombic space group P 2 1 2 1 2 1 . The dimeric (L-CysH⋯L-Cys) cation is formed due to a strong O–H⋯O hydrogen bond with an O⋯O distance of 2.498(2) Å. Phosphite anions in the structure are linked to infinite chains. An IR spectrum is recorded and discussed based on its structure.
