Summary

The extraction of tungsten(V) from hydrochloric acid with diethazine (DT) dissolved in chloroform has been studied. The composition of the extracted species was found to be (DTH+)2[WO (SCN)5 2−]. This complex, dissolved in chloroform, has maximum absorbance at 405 nm and a molar absorptivity of 1.46×104 l · mole−1 · cm−1.
