Abstract：

Two-dimensional　correlation　infrared　spectroscopy　(2D-COS)　were　employed　to　investigate　temperature-dependent　spectral　variations　[(PO4)2Mo5O15]6-,　β-[Mo8O26]4-,　[PMo12O40]3-,　[P2W18O60]6-　cluster　anions.　Two-dimensional　correlation　spectra　in　800-1000　cm-1　region　provides　information　about　the　variations　of　the　terminal　Mo{double　bond,　long}O　bonds　in　the　polyoxomolybdenum　(or　Polyoxotungstic)　cluster　anions.　In　600-800　cm-1　region,　it　reveals　the　information　about　the　variations　of　the　bridging　Mo{single　bond}O{single　bond}Mo　bonds　in　the　cluster　anions.　The　results　indicated　that　the　intensity　change　of　the　terminal　Mo{double　bond,　long}O　bonds　are　more　sensitive　than　the　bridging　Mo-O-Mo　bands　to　the　temperature　variation.　Furthermore,　from　[(PO4)2Mo5O15]6-,　β-[Mo8O26]　to　[PMo12O40]3-,　with　the　cluster　anions　becoming　larger,　the　2D-IR　spectra　showed　the　bridging　Mo-O-Mo　bonds　in　the　cluster　anions　were　becoming　more　sensitive　to　temperature　variation.　©　2008　Elsevier　B.V.　All　rights　reserved.
