摘要：

A novel isopolymolybdates functionalized by rare earth complexes namely, [La (eta(2)-NO3) (dmso)(7)](2) [beta- Mo8O26] (1) has been successfully synthesized and characterized by routine methods: IR, X-ray powder diffraction, UV-Visible absorption and single crystal X-ray diffraction. The title compound is crystallized in monoclinic space group P2(1)/n with a = 11.566 (2) angstrom, b = 28.522 (6) angstrom, c = 12.644 (3) angstrom, beta = 91.94 (3)degrees. The structural feature of 1 is that lanthanum complexes form a honeycomb network, in which resides the [beta-Mo8O26](4-) isomer. The cohesion structure is ensured by non typical hydrogen bonding interactions causes a 3D supramolecular network. Absorption spectrum, optical band gap energies have been investigated.
