文摘

The reactions of beryllium atoms with dioxygen were reinvestigated by matrix isolation infrared absorption spectroscopy. Besides the previously reported linear OBeO and cyclic Be₂O₂ molecules, two interconvertible beryllium ozonide complexes were prepared and characterized. The BeOBe(畏²-O₃) complex was formed on annealing, which is characterized to be a side-on bonded ozonide complex with a planar C_2v structure. The BeOBe(畏²-O₃) complex isomerized to the BeOBe(畏¹-O₃) isomer under visible light excitation, which is an end-on bonded ozonide complex with planar C_s symmetry. These two isomers are interconvertible; that is, visible light induces the conversion of the side-on bonded complex to the end-on bonded isomer, and vice versa on annealing. In addition, evidence is also presented for the linear BeOBeOBe cluster.
