Question

j. e. tackett and d. t. sawyer, properties and infrared spectra in the potassium bromide region of 8-quinolinol and its metal chelates, inorg. chem. 3, 692 (1964).

Answer 1

When the compounds are heated in an inert atmosphere it can be verified the consecutive partial sublimation, fusion, partial volatilization and partial thermal decomposition of the anhydrous complexes. When in an oxidating atmosphere the above process is only verified to Cu(II) chelates. Anhydrous copper(II) complexes present a monoclinic structure in the b form and the volatilized compound in a a form.
