Abstract
Five new coordination polymers, namely, [Zn 2(H 2O) 2(BBC)](NO 3)(DEF) 6 (DUT-40), [Zn 3(H 2O) 3(BBC) 2] (DUT-41), [(C 2H 5) 2NH 2][Zn 2(BBC)(TDC)] (DEF) 6(H 2O) 7 (DUT-42), [Zn 10(BBC) 5(BPDC) 2(H 2O) 10](NO 3)(DEF) 28(H 2O) 8 (DUT-43), and [Co 2(BBC)(NO 3)(DEF) 2(H 2O)](DEF) 6(H 2O) (DUT-44), where BBC - 4,4′,4′′- (benzene-1,3,5-triyl-tris(benzene-4,1-diyl))tribenzoate, TDC - 2,5-thiophenedicarboxylate, BPDC - 4,4′-biphenyldicarboxylate, DEF - N,N-diethylformamide, were obtained under solvothermal conditions and structurally characterized. It has been shown that compounds DUT-40, DUT-41 and DUT-44 exhibit 2D layered structures with large hexagonal channels. Utilization of additional angular dicarboxylic TDC linker led to the formation of the DUT-42 compound with the structure consisting of three interpenetrated 3D networks. Using the linear co-linker dicarboxylic BPDC, DUT-43 was obtained which forms a complicated 3D architecture arising from the polycatenation of triple-layered 2D building units and 2D single layer units. The pore accessibility of the synthesized compounds in the liquid phase was proved by the adsorption of dye molecules.
