Infrared Matrix-Isolation Studies of the Interactions and Reactions of Group 3A Metal Atoms with Water

It has been shown that aluminium atoms react spontaneously with H2O at 15 K while the heavier group 3A metals form M(*)OH2 and M2(*)OH2 adducts.Adduct formation causes the ν2-bending mode of H2O to decrease by 21.4, 16.5, and 9.6 cm-1 for Ga, In, and Tl and 14.4 and 10.6 cm-1 for Ga2 and In2, respectively.The divalent HAlOH molecular species is formed from reaction of the aluminium atom with water.The HGaOH and HInOH molecular species are formed by photolysis of the respective adducts while the Tl(*)OH2 adduct does not react on photolysis.The monovalent molecular species MOH is readily formed by further photolysis of the divalent HMOH species.Molecular vibrational frequencies and mode assignments are given in accompanying tables.Data suggest that the diatomic Ga2, In2, and Tl2 adducts with water readily rearrange when photolyzed to a hydrogen-bridged dimetal species, which in turn is converted to the M2O molecular species by further photolysis.
