Alkali-metal peroxocarbonates, M2[CO3]·nH2O2, M2[C2O6], M[HCO4]·nH2O, and Li2[CO4]·H2O

Abstract

The vibrational spectra of normal and ²H-enriched carbonate perhydrates M₂[CO₃]·nH₂O₂(Na,n= 1.5; K, Rb, or Cs, n= 3; NH₄n= 1) and those of the normal and ¹³C-enriched peroxodicarbonates M₂[C₂O₆](M = Na, K, Rb, or Cs), normal and ¹³C-enriched Li₂[CO₄]·H₂O, and the salts M[MCO₄]·nH₂O (Na, n= 1; K, or Rb, n= 0) have been recorded. Structures are proposed for these species. E.s.r. measurements indicate that some of these materials contain free radicals, the nature of which have been investigated.
