Different types of polyoxometalate-directed diverse architectures derived from the rigid ligand pyrazine-bis(triazole): assembly, electrocatalysis, and dye adsorption

Three new polyoxometalate (POM)-based metal–organic complexes, {Ni3(Hpytty)2[AlMo6(OH)5O19](H2O)4(CH3O)}·5H2O (1), {Ni3(Hpytty)2 [CrMo6(OH)5O19](H2O)10}·6H2O (2), and {Co2(pytty)[γ-Mo8O26]0.5 (H2O)...
