| Abstract: | The coordination polymers (CPs) {Cd(Pydc)(H2O)3] · PydcH2} (I) and Mn(Pydc)(H2O)3] · PydcH2} (II) were obtained by the reaction of CdSO4 · 5H2O or MnCl2 · 4H2O with pyridine-2,6-dicarboxylic acid (PydcH2). The structures of the CPs I and II were characterized by IR, UV-Vis, TGA, and X-ray single crystal analysis (CIF files CCDC nos. 1417757 (I), 1417758 (II)). The network structures of I and II are constructed by an infinite number of discrete binuclear molecules and free PydcH2. The structures of the CPs I and II connected by the extensive H-bonds and π–π stacking, forming a 3D-network. The CPs I and II were screened to test their antimicrobial activities against different species of bacteria and fungi. |
