A family of 2D and 3D coordination polymers involving a trigonal tritopic linker

Five new coordination polymers, namely, [Zn2 H2O 2 BBC ] NO3 DEF 6 DUT 40 , [Zn3 H2O 3 BBC 2] DUT 41 , [ C2H5 2NH2][Zn2 BBC TDC ] DEF 6 H2O 7 DUT 42 , [Zn10 BBC 5 BPDC 2 H2O 10] NO3 DEF 28 H2O 8 DUT 43 , and [Co2 BBC NO3 DEF 2 H2O ] DEF 6 H2O DUT 44 , where BBC 4,4 amp; 8242;,4 amp; 8242; amp; 8242; benzene 1,3,5 triyl tris benzene 4,1 diyl tribenzoate, TDC 2,5 thiophenedicarboxylate, BPDC 4,4 amp; 8242; 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 molecule
