Conclusions
-
1.
Mononitrates, dinitrates, monochlorides, and trichlorides of hafnium chelates were prepared.
-
2.
It was noted that, as a result of the isomorphous crystal structures of corresponding zirconium and hafnium compounds, the melting points of analogous chelates were the same or nearly so.
