• A new 3D POMOF hybrid compound with helix and 12-nuclear cycles structure is reported.
• The whole 3D framework contains helix and cycles double configuration tunnel along c axis.
• The new compound exhibits good photocatalytic degradation of RhB.
A new 3D hybrid compound based on polyoxometalates (POMs), [Ag6(Hpyttz) (pyttz) (H2O)][PMo12O40] (pyttz = 3-(pyrid-2-yl)-5-(1H-1,2,4-triazol- 3-yl)-1,2,4-triazolyl), has been hydrothermally synthesized and structurally characterized by routine techniques. X-ray diffraction analysis reveals that the title compound is constructed by the 2D Ag-pyttz coordination polymer with 12-nuclear cycles and Ag-POM inorgnaic architecture. The whole 3D framework contains the helix and cycles double configuration tunnels, which is formed by the right- and left-helical chain linking with TMCs subunit in hand-in-hand mode. Note that such structural feature is rare in POMOF system. Unfortunately, because of the opposite direction of the helical chains spiral inward, the tunnels are occupied by the {PMo12} clusters. Furthermore, the title compound exhibits good photocatalytic activity toward degradation of RhB.
