Abstract:
A novel-type 3D polyoxomolybdate-organic framework, {[Cu3(H3tpb)2(tpb)(Mo4O12)]·4H2O}n (1, H3tpb = 1,3,5-tri(1H-pyrazol-3-yl)benzene), was prepared and characterized by elemental analysis, IR spectroscopy, and luminescence analysis. Single-crystal X-ray diffraction analysis reveals that novel neutral triple helix {Mo4O12}n chains are encased in bowl-like 2D [Cu3(H3tpb)2(tpb)]n intervals via bond interactions between terminal oxygen atoms and cations of Cu(I), leaving an unprecedented (3,3,5,8)-connected (3·4·6(8))3(3(6)·4(6)·8(6)·9(6)·10(4))(4(3))2(6(3)) topology. Moreover, compound 1 exhibits remarkable photocatalytic activities for decomposition of methylene orange (MO), methylene red (MR), methylene blue (MB), methylene violet (MV), and rhodamine B (RhB) under UV light.

In these complexes, transition metals form coordinate covalent bonds, a kind of Lewis acid-base interaction in which both of the electrons in the bond are contributed by a donor (Lewis base) to an electron acceptor (Lewis acid). The Lewis acid in...
