Abstract

An organic molecule containing krypton, HKrCCH, is reported. The preparation of HKrCCH includes 193-nm photolysis of H₂C₂/Kr solid mixtures at 8 K and subsequent thermal mobilization of hydrogen atoms at ≥30 K. The identification is based on infrared absorption spectroscopy and supported by ab initio calculations which show ionic and covalent contributions to the bonding. We believe that a series of similar organokrypton molecules can be prepared as computationally demonstrated for HKrC₄H and HKrC₃H₃. These results feature a generally novel way for activating chemically the H-C_≡C- group, which can find practical applications of the krypton catalysis.
