Abstract
A novel isopolymolybdates functionalized by rare earth complexes namely, [La (η2-NO3) (dmso)7]2 [β-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 P21/n with a = 11.566 (2) Å, b = 28.522 (6) Å, c = 12.644 (3) Å, β = 91.94 (3)°. The structural feature of 1 is that lanthanum complexes form a honeycomb network, in which resides the [β-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.
