A pure inorganic 1D chain based on {Mo8O28} clusters and Mn(II) ions: [Mn(H2O)2Mo8O28]n6n−

Abstract A new pure inorganic polymer, (NH 4 ) 6 n [Mn(H 2 O) 2 Mo 8 O 28 )] n (H 2 O) 2 n (1) , has been synthesized and characterized by elemental analyses, IR spectrum, UV–vis absorption spectra, TG-DSC and electrochemical studies. In 1 , [Mo 8 O 28 ] 8− anions act as tetradentate ligands and are alternately linked by Mn ( H 2 O ) 2 2 + ions into a one-dimensional chain structure. It is interesting that 1 represents the first example of pure inorganic–inorganic hybrid based on octamolybdate and transition metal ions. Moreover, it was indicated that 1 had definite catalytic activities on the probe reaction of benzyl alcohol oxidation to benzaldehyde with H 2 O 2 .
