Iron(III) nitrate is deliquescent, and it is commonly found as the nonahydrate Fe(NO 3) 3 ·9H 2 O, which forms colourless to pale violet crystals. This compound is the trinitrate salt of the aquo complex [Fe(H 2 O) 6] 3+. [4] Other hydrates Fe(NO 3) 3 ·x H 2 O, include:
Iron(II) nitrate can be produced in multiple ways, such as the reaction of iron metal with cold dilute nitric acid: . 3 Fe + 8 HNO 3 + 12 H 2 O → 3 Fe(NO 3) 2 (H 2 O) 6 + 2 NO. If this reaction is conducted below -10 °C, nonahydrate is produced.

Aluminium nitrate may also be prepared a metathesis reaction between aluminium sulfate and a nitrate salt with a suitable cation such as barium, strontium, calcium, silver, or lead. e.g. Al 2 (SO 4) 3 + 3 Ba(NO 3) 2 → 2 Al(NO 3) 3 + 3 BaSO 4.
It often occurs as the trihydrate K 3 [Fe(C 2 O 4) 3]·3H 2 O. Both are crystalline compounds, lime green in colour. [4] The compound is a salt consisting of ferrioxalate anions, [Fe(C 2 O 4) 3] 3−, and potassium cations K +. The anion is a transition metal oxalate complex consisting of an iron atom in the +3 oxidation state and three ...

Iron has five nitrides observed at ambient conditions, Fe 2 N, Fe 3 N 4, Fe 4 N, Fe 7 N 3 and Fe 16 N 2.They are crystalline, metallic solids. Group 7 and group 8 transition metals form nitrides that decompose at relatively low temperatures—iron nitride, Fe 2 N decomposes with loss of molecular nitrogen at around 400 °C and formation of lower-nitrogen content iron nitrides.
