Dl-Piperidinium-2-carboxyl-ate bis-(hydrogen peroxide): unusual hydrogen-bonded peroxide chains.

ABSTRACT: The title compound, C₆H₁₁NO₂·2H₂O₂, is the richest (by molar ratio) in hydrogen peroxide among the peroxosolvates of aliphatic α-amino acids. The asymmetric unit contains a zwitterionic pipecolinic acid mol-ecule and two hydrogen peroxide mol-ecules. The two crystallographically independent hydrogen peroxide mol-ecules form a different number of hydrogen bonds: one forms two as donor and two as acceptor ([2,2] mode) and the other forms two as donor and one as acceptor ([2,1] mode). The latter hydrogen peroxide mol-ecule forms infinite hydrogen-bonded hydro-peroxo chains running along the c-axis direction, which is unusual for aliphatic α-amino acid peroxosolvates.
