Abstract

The interactions of water molecule with platinum dioxygen complex and dioxide molecule are investigated by means of matrix isolation infrared spectroscopy and density functional calculations. The platinum atoms reacted with dioxygen to form the previously reported Pt(O(2)) complex. The Pt(O(2)) complex reacted with water molecule to give the Pt(O(2))-H(2)O complex, which was characterized to involve hydrogen bonding between one O atom of Pt(O(2)) and one H atom of H(2)O (structure A). Upon visible light irradiation, the hydrogen bonded Pt(O(2))HOH complex rearranged to another Pt(O(2))-H(2)O isomer (structure B), which involves (O(2))PtOH(2) interaction. The Pt(O(2))-H(2)O complex in structure B can be isomerized to the weakly bound platinum dioxide-water complex (structure C) under UV irradiation.
