摘要：
Reaction of Na2CO3, Pr6O11 and H3PO4 gave the sodium praseodymium polyphosphate NaPr(PO3)(4). The title compound crystallized in the monoclinic P2(1)/n space group with a=0.9965(4) nm, b=1.31437(4) rim, c=0.72271(3) run. beta=90.429(3)degrees, V=0.9465(4) nm(3), Z=4, R=0.0493 and wR=0.1266 for 1855 independent reflections. The structure of NaPr(PO3)(4) consisted of PrO8 polyhedra sharing oxygen atoms with phosphoric group PO4 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.
