Thermolysis of a Mixture of [Pd(NH)]Cl and (NH)[HWO] in an Inert Atmosphere

The features of the thermolysis of a mixture of tetraamminepalladium(II) dichloride with ammonium paratungstate were studied. The products were analyzed by X-ray diffraction, thermal analysis, and mass spectrometry. It was shown that thermolysis proceeds through the reduction of palladium and tungsten. The reducing agent is inner-sphere ammonia in statu nascendi, initiating the reduction of palladium, which induces the reduction of tungstate ions with the formation of a solid solution. It was shown that the reduction of a base refractory metal is facilitated by the presence of a noble metal, and the stabilization of tungsten by palladium atoms leads to the formation of an ordered solid solution.
