Abstract
AbstractThe compound Pb2PO4I was synthesized via a solid state reaction under inert conditions. None of the known structure types of other compounds of the type M2(P,V,As,Cr)O4(F,Cl,Br,I) provided a similar pattern. Structure solution was carried out by evaluation of an X‐ray diffractogram of polycrystalline powder using the methods simulated annealing and difference Fourier. Pb2PO4I crystallizes in the space group P21/c with the lattice parameters a = 9.0451(1) Å, b = 8.7593(1) Å, c = 8.5740(1) Å, and β = 111.128(1)°. The isotypic compounds Sr2PO4I and Ba2PO4I were synthesized, too. Their crystallographic structure was refined by Rietveld analysis. The structure of the three compounds is described and discussed.
