Solvothermal reaction of 3-aminoisonicotinic acid(Haina) and Cu(NO_3)_2·2.5H_2O gave a novel twodimensional(2D) microporous metal–organic framework, [Cu(aina)_2(DMF)]·DMF(1, DMF = N,N-dimethylformamide). Single-crystal X-ray crystallographic study of compound 1 revealed that Cu(II)ions are linked by ainaàligands forming square grid-like layers, which stack together via multiple hydrogen bonding interactions. The solvent-free framework of 1a displayed considerable porosity(void = 46.5%) with one-dimensional(1D) open channels(4.7 ? ? 4.8 ?) functionalized by amino groups.Gas sorption measurements of 1 revealed selective carbon dioxide(CO_2) and acetylene(C_2H_2) adsorption over methane(CH_4) and nitrogen(N_2) at ambient temperature.
Solvothermal reaction of 3-aminoisonicotinic acid (Haina) and Cu (NO_3) _2 · 2.5H_2O gave a novel twodimensional (2D) microporous metal-organic framework, [Cu (aina) _2 (DMF) , N-dimethylformamide. Single-crystal X-ray crystallographic study of compound 1 revealed that Cu (II) ions are linked by a nanoàligands forming square grid-like layers, which stack together via multiple hydrogen bonding interactions. The solvent-free framework of 1a displayed considerable porosity (void = 46.5%) with one-dimensional (1D) open channels (4.7 · 4.8 ·) functionalized by amino groups. Gas sorption measurements of 1 exposed selective carbon dioxide (CO_2) and acetylene (C_2H_2) methane (CH_4) and nitrogen (N_2) at ambient temperature.
