Samarium(III) phosphate is an inorganic compound, with the chemical formula of SmPO4. It is one of the phosphates of samarium.
Preparation
[edit]Samarium(III) phosphate can be obtained by reacting sodium metaphosphate with any soluble samarium(III) salt:
Samarium(III) phosphate can also be obtained by reacting phosphoric acid and samarium(III) chloride.[1]
Properties
[edit]Samarium(III) phosphate reacts with sodium fluoride at 750 °C to form Na2SmF2PO4.[2] Samarium(III) phosphate forms crystals of the monoclinic crystal system, with space group P21/n, and lattice parameters a = 0.6669 nm, b = 0.6868 nm, c = 0.6351 nm, β = 103.92 °, Z = 4.[3]
