A new 3D metal–organic framework (MOF) derived from the 1D [Mo₃O₁₀]_n²ⁿ⁻ chains and the flexible N,N'-bis(5-methyl-2-pyrazinecarboxamide)-1,2-ethane (bmpae), [Cu(bmpae)_0.5(Mo₃O₁₀)(H₂O)]·H₂O (1) has been hydrothermally synthesized. Crystal analysis reveals that complex 1 is a 3D polyoxometalate (POM)-based MOF containing the 2D [Cu(bmpae)_0.5]_n²ⁿ⁺ metal–organic layers and the 1D inorganic [Mo₃O₁₀]_n²ⁿ⁻ chains. The electrochemical behaviors and electrochemical sensing property of the title complex were studied, and its adsorption capacities towards organic dyes gentian violet (GV) and methylene blue (MB) were also investigated.

从1D [Mo ₃ O ₁₀ ] _n ^2n-链和柔性N，N'-双（5-甲基-2-吡嗪甲酰胺）-1,2-乙烷（bmpae ）衍生的新3D金属有机框架（MOF）），已经水热合成[Cu（bmpae）_0.5（Mo ₃ O ₁₀）（H ₂ O）]·H ₂ O（1）。晶体分析表明，配合物1是基于3D多金属氧酸盐（POM）的MOF，包含2D [Cu（bmpae）_0.5 ] _n ^{2n +}金属-有机层和1D无机[Mo ₃ O ₁₀ ] _n ^2n-链。研究了标题配合物的电化学行为和电化学传感性能，并研究了其对有机染料龙胆紫（GV）和亚甲基蓝（MB）的吸附能力。
