A Series of Isostructural Polyoxometalate-Based Metal–Organic Frameworks of 3,5-Bis(1',2',4'-triazol-1'-yl)pyridine: Synthesis, Structures and Electrocatalytic Properties

Three isostructural polyoxometalate-based metal–organic frameworks [MII2(btap) 2 (β-Mo 8 O 26 )(H 2 O) 4 ]·4H 2 O were synthesized, and thermal derivatives of them were used as OER catalysts.
