| Abstract: The complex [Na(Bl5C5)(H2O)]2[Co(NCS)4] has been grown in a gel reaction and characterized by elemental analyses, solution ability, mol conductivity, differential thermal and thermogravimetric analyses as well as infrared spectra. The molecular and crystalline structure of the complex has been determined by four-circle X-ray diffractometer.The melting point of this blue complex crystal is 161.0～162.0℃. The crystal dissolves in organic solvents with stronger polarity. The mol conductivity in ethanol shows that it is 2 - 1 type complex. Its loss-water process at 129℃, melting temperature and biggest thermo-decomposition effect at 364℃ are indicated in differential thermal and thermogravimetric curves. The exist of thiocyanates, the crown ether and water are showed in the infrared spectra of the complex. Results of the structure analysis of the complex single crystal indicate that the sodium ion coordinates with the crown ether and water molecule, and the sodium ion eater into the cavity of the crown ether; the cobalt(Ⅱ) ion coordinates tetrahedrally with four thiocyanates; the combination between two kinds of the coordination ions is due to electrostatic effect. |
