Samarium(III) phosphate is an inorganic compound, with the chemical formula of SmPO4. It is one of the phosphates of samarium.
Preparation
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
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]
