| Abstract: | Three divalent transiton‐metal complexes of 2,3‐pyridinedicarboxylate (2,3‐pda2), [Mn(2,3‐pda)‐(H2O)3]∞ ( 7 ), [Ni(2,3‐pda)(H2O)3]∞ ( 8 ), and [Cd2(2,3‐pda)2(H2O)]∞ ( 9 ) have been hydrothermally synthesized and structurally characterized. X‐ray diffraction analyses reveal that compounds 7 and 8 are zigzag‐ and linear‐type one‐dimension (1D) coordination polymers, respectively, whereas compound 9 is a three‐dimension (3D) coordination polymer. A simple comparison of the coordination geometries with the available neutral analogues {Mx(2,3‐pda)x(H2O)y}∞ containing one or two divalent transition‐metal atoms and equal ligands in the presence or absence of coordinated water molecules is also presented. |
