Abstract

Three new double complex compounds with the following compositions were obtained:[Cd(thio)4]·[Cd(SCN)4],[Cd(thio)4]·[Co(SCN)4], [Cu(thio)4] [Cd2(SCN)6].

Some of their physical properties including melting points and electric conductivity have been determined. The study of their IR-spectra shows that the metal-thiourea bond in the complex cation is formed via the sulphur atom. The Co-SCN bond in the complex anion [Co(SCN)4]2− is formed through the nitrogen atom, and in [Cd(SCN)4]2− the cadnium-thiocyanate bond is probably formed with some groups through the sulphur atom, and with others through the nitrogen.

In the complex anion [Cd2(SCN)6]2− the IR spectral data show that a bridging bond is also formed.
