Palladium (II) sulfate is an inorganic chemical compound of palladium from the group of sulfates .

Extraction and presentation

Palladium (II) sulfate hydrate can be obtained by reacting palladium (II) nitrate with sulfuric acid at 80 ° C. By reacting the hydrate with concentrated sulfuric acid at 250 ° C, the leaves anhydrate win.

properties

Palladium (II) sulfate is a red-brown solid that hydrolyzes in water and is poorly soluble in dilute sulfuric acid. The crystal structure is monoclinic in the space group C 2 / c (space group no. 15) . Each palladium atom is coordinated in a square-planar manner by four sulfate ions, which in turn are bound to three further palladium atoms. Template: room group / 15
