The alkali metal decamolybdate of ideal formura, A_2O・10MoO_3・nH_2O, form a structurally related family.[1] The complete crystal structures of two members of which, A=K, Na, have been determined.[2, 3] For both, the framework structure consists of double chains of edge-sharing MoO_6 octahedra linked by common corners which form wide (0.29nm diameter) tunnels occupied by the alkali metal ion (Fig. 1). For all these compounds the presence of wide one-dimensional tunnels suggest that there should be a rich intercalation chemistry and related properties to investigate. In this report, There are no published quantitative active energy data of decomposition available for Li and Na-decamolybdates and we present the determination of their active energies of decomposition here.
