Scandium thiocyanate
WebThe current discussion on whether scandium, yttrium and lanthanum should represent Group 3 in the Periodic Table or whether lutetium should replace lanthanum in the group has prompted us to further explore the structural chemistry of the Group 3 elements and compare the coordination numbers and coordination geometries adopted. The steric and … WebThe reactions of scandium(III) chloride and thiocyanate with 2,2′-bipyridyl (bipy) and 1,10-phenanthroline (phen) have been investigated.Conductivity and i.r. studies suggest that scandium(III) is hexaco-ordinated in all the complexes, and the products can be formulated as [ScL 3](CNS) 3 and [ScL 2 X 2]X (L = bipy, phen; X = CNS –, Cl –) For the latter species, …

WebSubscribe today Scandium is separated from the other rare earths by precipitation of the insoluble potassium scandium sulfate or by extraction of scandium thiocyanate by diethyl ether. The metal itself was first prepared in 1938 by the electrolysis of potassium, lithium, and scandium chlorides in a eutectic mixture (i.e., a mixture having the lowest melting … WebA method is described for the separation of scandium from rare earths and thorium by anion exchange. The method utilises the adsorption of a negatively-charged thiocyanato …

WebThe formula for mercury (I) chloride is Hg2Cl2. Unlike other transition metals, the 1+ cation of mercury has the formula Hg22+ and behaves like a polyatomic ion. What is the formula for mercury (II) nitride? The formula for mercury (II) nitride is Hg3N2. Mercury has a 2+ charge, as indicated by the roman numeral, and nitride has a 3- charge.
