✦ Synopsis

Two new octamolybdate-based inorganic-organic hybrid compounds Ni II (HL) 2 (H 2 O) 2 (b-Mo 8 O 26 ) (1) and Cu I 4 L 4 (b-Mo 8 O 26 ) (2) (L = 3-((1H-1,2,4-triazol-1-yl)methyl)pyridine) have been hydrothermally synthesized and structurally characterized. Compound 1 is built up of octamolybdate anions [b-Mo 8 O 26 ] 4À covalently linked by [Ni(HL) 2 (H 2 O) 2 ] 4+ cations into 1D infinite chains and was further connected by hydrogen bonds into a 3D supramolecular structure. Compound 2 is constructed from [b-Mo 8 O 26 ] 4À building blocks and [Cu 2 L 2 ] 2n

4n+ strands to form a 3-connected 2D network. Furthermore, the diffuse reflectance spectra reveal that these two inorganic-organic hybrid compounds are potential wide gap semiconductor materials.
