A new rhombic 2D interpenetrated organic-inorganic hybrid material base on [HxAs2Mo6O26](6 − x)− polyoxoanion and Co-btb complexes

Compound 1 represents a rhombic 2D interpenetrated layer structure based on unconventional arsenomolybdate [H2As2Mo6O26]4 − polyoxoanion and transition-metal complex [Co(btb)(H2O)2]2 +, which possess obvious electrocatalytic activities toward the reduction of NaNO2 and better photocatalytic activities for the degradation of methylene blue and rhodamine-B.132
