A multifunctional reduced molybdophosphate-based 3D metal–organic framework induced by a rigid triazole and a flexible bis(triazole) mixed ligand

•A 3D MOF (1) derived from molybdophosphate and mixed ligands was obtained.•1 shows a (2,3,8)-connected network with {{4·62}2{44·62·818·124}{4}2} topology.•1 represents the first 3D P4Mo6-based MOF constructed by mixed N-donor ligands.•1 shows good electrocatalytic and selective photocatalytic activities for MB.

A novel reduced molybdophosphate-based metal–organic framework (MOF) Zn[(MoO2)6(HPO4)2(PO4)2(OH)3]2[Zn2(L1)][Zn(HL2)2]2·10H2O (1) (L1 = 1,6-bis(1,2,4-triazol-1-yl)hexane, L2 = 1,2,4-triazol) has been hydrothermally synthesized and structurally characterized. Compound 1 is constructed from the [Zn(P4Mo6)2]-based 2D layer and μ2-bridging L1 ligands, which shows a (2,3,8)-connected three-dimensional framework with {{4·62}2{44·62·818·124}{4}2} topology. 1 represents the first 3D P4Mo6-based MOF constructed by mixed N-donor ligands. The electrocatalytic and photocatalytic activities of compound 1 have been investigated.
