| Abstract: | The complexes obtained from ethyleneselenourea and cobalt(II) halides have been prepared and characterized. They have formula CoL2X2 (X = Cl, Br, I), tetrahedral stereochemistry and they are Se-bonded to the cobalt(II). They are comparatively studied with the previously reported complexes of cobalt(II) with ethylenethiourea, by IR and visible spectroscopy and magnetic susceptibilities. Using the average linand field approximation, the ethyleneselenourea is located at the very low end of the nephelauxetic series. |
