| 摘 要： | A new MOF Li2(muc)(H2O)2] (1,H2muc = mucic acid) has been synthesized and characterized. 1 crystallizes in the monoclinic system,space group P21/c with a = 4.7884(1),b = 19.4618(5),c = 5.3639(2) ,β = 96.628(2)°,V = 496.53(2) 3,Z = 2,Mr = 258.04,Dc = 1.726 Mg/m3,F(000) = 268,μ = 0.164 mm-1,the final R = 0.0311 and wR = 0.0845 for 946 observed reflections with I 2σ(Ⅰ). The 2D undulating layers are extended into a 3D supramolecular network via hydrogen bonds. The 2D layer structure can be rationalized as an unusual binodal 4-connected network with kgm topology. Cyclic voltammetry curves exhibit one pair of redox peaks and two reduction waves.
