Two novel complexes of CoL1(SCN)(2)(H2O)(2)center dot 4H(2)O (1) and COL2(SCN)(2)(H2O)(2)center dot 2H(2)O (2) (L-1 = bis(4-pyridinecarboxamide)-1,2-ethane-N,N'-dioxide and L-2 = bis(4-pyridinecarboxamide-1,6-hexane)-N,N'-dioxide) constructed by pre-designed ligands of bis(4-pyridinecarboxamide)alkanes-N,N'-dioxide have been synthesized and structurally characterized. Both compounds contain similar 1D chains bridged by the ligands. However, the chains in 1 and 2 are connected by different interchain hydrogen bonds to form different 2D layers, which depend on the flexibility and length of the ligands. Furthermore, the thermal stability of 1 and 2 were studied by using thermogravimetric analysis and temperature dependent powder X-ray diffraction method.
