Two new 2D metal-organic framework materials, [Cu(Br2BDC)(2)](HTEA)(2) (1)and [Co-2(Br2BDC) (HCOO)(2)(DMF)(2)] (2)(Br2BDC = 2,5-dibromoterephthalate, DMF = dimethylformamide, TEA = triethylamine), have been synthesized through solvothermal reactions. Compound 1 consists of anionic layered networks balanced with HTEA(+) cations located between the layers. The layered network of 1 is a uninodal 4-connected net in which copper ions act as the uninodals and the Br2BDC ligand as the linkers. The structure of 2 is a neutral 2D coordination network containing hexagonal rings of clusters formed by six CoO6 octahedra. The topology of the 2D network in 2 is a uninodal 6-connected net with the clusters as the nodals. In both compounds, the stacking of the layers forms one-dimensional channels. The electrochemical performance of compounds 1 and 2 was also studied using cyclic voltammetry and electrochemical impedance spectroscopy. (C) 2016 Elsevier B.V. All rights reserved.
