The crystal and molecular structure of molybdenyl phenylphosphonate has been determined from X-ray powder diffraction data and refined by Rietveld methods. The compound crystallizes in the orthorhombic space group P222 with a = 6.3610(3), b = 16.0889(9), c = 9.3573(7) Å, Z = 4. The final agreement factors are Rp = 0.119, Rwp = 0.175, RF = 0.056. The structure consists of bent MoO2 groups coordinated by three phosphonate oxygens and a water molecule. The bridging of the phosphonate group leads to the formation of double chains which are held together by hydrogen bonds involving water oxygens and phosphonate oxygens. The structure is similar to that of MoO2(O3PC6H5).H2O and the phosphonate also exhibits intercalation behavior toward amines. © 1995, American Chemical Society. All rights reserved.
