【Abstract】 The title stoichiometric complex has been prepared in a gel column of 18-crown-6 and tested by infrared, mass spectra, thermal analywes as well as other physical characters. The testing results and determined structures of the complex have been discussedThe red shiff of C-O-C stretching vibration frequencies in IR indicated the coordination of the crown ether. The [M1-1]+ and [M1 + 1] + peaks from the crown parent M₁⁺ , the M₂⁺ parent peak and [M2 + 2] + peak of tetrathiocyanatocobalt group present all in MS of the complex. By thermal analyses, DTA, TG and DTG curves of the complex its loss of water, phase change and thermal decomposition were discussed.更多还原
