Synthesis and characterization of crystalline polymeric carbonic acid (H2CO3) with s p 3-hybridized carbon at elevated pressures

Abstract The existence of polymeric carbonic acid (H2CO3) at elevated pressures has been predicted, but has not been investigated experimentally. Here, polymeric carbonic acid containing s p 3-hybridized carbon was synthesized and characterized at  ≈40 GPa. H2CO3 single crystals were obtained by las...
