Thermal and Photolytic Reactions of Group 12 Metal Atoms in HCl-Doped Argon Matrixes:Formation and Characterization of the Hydride Species HMC1(M=Zn,Cd,or Hg)

摘要

IR and UV-vis spectroscopic measurements have been used to chart the thermal and photolytic reactions occurring in HCl-doped Ar matrixes containing Zn,Cd,or Hg atoms(M).Following the formation of a loosely bound metal atom adduct M…HC1,the primary reaction induced by UV irradiation(200 < A < 400 nm)is insertion of M into the H-Cl bond to give the molecule HMC1,which has been characterized by its IR spectrum,with assignments validated by the effects of isotopic change(~（1,2）H,~(35.37)C1,and ~(64,66,68)Zn)and by the results of density functional theory calculations.The properties of HMC1 are compared with those of other Group 12 metal hydrides,and the mechanism of insertion is also discussed.
