Abstract
Abstract Reaction of Na 2 CO 3 , Pr 6 O 11 and H 3 PO 4 gave the sodium praseodymium polyphosphate NaPr(PO 3 ) 4 . The title compound crystallized in the monoclinic P 2 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.
