Synthesis and crystal structure of sodium praseodymium polyphosphate, NaPr(PO 3) 4

Reaction of Na 2CO 3, Pr 6O 11 and H 3PO 4 gave the sodium praseodymium polyphosphate NaPr(PO 3) 4. The title compound crystallized in the monoclinic P2 1/ n space group with a=0.9965(4) nm, b=1.31437(4) nm, c=0.72271(3) nm, β=90.429(3)°, V=0.9465(4) nm 3, Z=4, R=0.0493 and wR=0.1266 for 1855 indepe...

Zusammenfassung:Reaction of Na 2CO 3, Pr 6O 11 and H 3PO 4 gave the sodium praseodymium polyphosphate NaPr(PO 3) 4. The title compound crystallized in the monoclinic P2 1/ n space group with a=0.9965(4) nm, b=1.31437(4) nm, c=0.72271(3) nm, β=90.429(3)°, V=0.9465(4) nm 3, Z=4, R=0.0493 and wR=0.1266 for 1855 independent reflections. The structure of NaPr(PO 3) 4 consisted of PrO 8 polyhedra sharing oxygen atoms with phosphoric group PO 4 to form a three-dimensional framework, delimiting intersecting tunnels in which the sodium ion was located. Each Na + ion was bonded to seven oxygen atoms.
