Abstract: Abstract One water stable three-dimensional coordination polymer {[Zn(TTPA)]·1.5DMA}n (Zn-1) was successfully synthesized via solvo-thermal reaction of a bifunctional ligand 2,5-bis-(1,2,4-triazol-1-yl)-terephthalic acid (H2TTPA) and Zn(NO3)2. Single-crystal X-ray diffraction analyses proclaimed that Zn-1 is a 3D framework… read more here.
