What is it about?

For 70 years the nuclear chemists working in Russia, USA, France, Germany the field of technetium chemistry were deeply intrigued by the incomprehensible behavior of the compound , to which the simplest structure HTcO4 had previously been attributed. Its behavior and properties differed drasically from those exhibited by the nearest "analogues neighbor" - rhenium. In this investigation we managed to find an explanation for these anomalies and discover a new class of inorganic compounds - polyoxotechnetates.

Why is it important?

A new class of inorganic compounds - polyoxotechnetates - have been discovered. It differs from other polyoxometallates by its stability in strong acids and the ox-red behaviour.


After such discovery the long line of polyoxometallated stable in acids are awaited.
