Assembly of a New 3D Octamolybdate‐based Compound: Using the Flexible Bis(triazole) ligand with a –(CH 2 ) 6 – Spacer

Through utilizing the flexible bis(triazole) ligand 1, 6‐bis(1, 2, 4‐triazol‐1‐yl)hexane (btx), a new octamolybdate‐based compound, [Cu 2 (btx) 4 (β‐Mo 8 O 26 )] · H 2 O ( 1 ), was synthesized under hydrothermal conditions. It was characterized by single‐crystal X‐ray diffraction, elemental analyses, IR spectroscopy, thermogravimetric analysis, and cyclic voltammetry. In compound 1 , the [β‐Mo 8 O 26 ] 4– anion acts as a bi‐connected inorganic linkage to connect the Cu‐btx moieties. The Cu1‐btx moiety linked by the [β‐Mo 8 O 26 ] 4– anions exhibits a 2D layer, while the Cu2‐btx moiety also shows a similar 2D layer. Furthermore, these two 2D moieties construct a 3D framework through sharing the same N7‐containing btx ligands.
