Abstract
IN the two decades since rhenium (Mendeléeff's dwi-manganese) was discovered, hundreds of its compounds have been reported. Among the latest are some stable complexes in which the element is present as the cation. Lebedinský and Ivanov-Emin (J. Gen. Chem., U.S.S.R., 13, 253; 1943) have described the complexes derived from saturated solutions of the double chlorides, K3ReCl6 and K2ReCl6, by using a large excess of ethylene diamine. This is apparently the only suitable base, since ammonia and pyridine do not react in the same way. During the reaction, rhenium oxidizes to the pentavalent state and ReO2(C2H4N2H4)2Cl separates. It gives no precipitates in aqueous solution except with cobaltinitrites and platinichlorides.
