| Abstract: | The self‐assembly reactions of Co(NCS)2 with diester‐bridged pyridine‐based ligands pyCO2‐(CH2)m‐O2Cpy (py = 4‐pyridyl; m = 2, 3, 4) have been studied. Interestingly, while Co(NCS)2 reacted with pyCO2‐(CH2)2‐O2Cpy (La) in MeOH/H2O or THF/MeCN to yield two coordination polymers Co(NCS)2(La)2]n (1)andCo(NCS)2(La)2‐2THF]n (2), reactions of Co(NCS)2 with pyCO2‐(CH2)3‐O2Cpy (Lb) in MeOH/MeCN and Co(NCS)2 with pyCO2‐(CH2)4‐Q2Cpy (Lc) in EtOH/H2O afforded Co(NCS)2(Lb)20.5MeOH]n (3) and Co(NCS)2(Lc)2‐2H2O]n (4), respectively. The X‐ray diffraction analyses indicated that polymers 1–4 consist of a one‐dimensional Co(II) chain in which each of the two adjacent Co(II) ions is bridged by two pyCO2‐(CH2)m‐O2Cpy ligands to form a macrocycle. In addition, the structures of polymers 1–4 were also characterized by infrared spectroscopy, thermogravimetry and elemental analysis. |
