Palladium(II) nitrate is the
inorganic compound
In chemistry, an inorganic compound is typically a chemical compound that lacks carbon–hydrogen bonds, that is, a compound that is not an organic compound. The study of inorganic compounds is a subfield of chemistry known as '' inorganic chemist ...

deliquescent solids. According to
X-ray crystallography, both compounds feature square planar Pd(II) with unidentate nitrate ligands. The anhydrous compound, which is a
coordination polymer
A coordination polymer is an inorganic or organometallic polymer structure containing metal cation centers linked by ligands. More formally a coordination polymer is a coordination compound with repeating coordination entities extending in 1, 2, o ...

Preparation
Hydrated palladium nitrate may be prepared by dissolving
palladium oxide hydrate in dilute nitric acid followed by crystallization. The nitrate crystallizes as yellow-brown
deliquescent prisms. The anhydrous material is obtained by treating palladium metal with fuming
nitric acid.
