Preparation and Characterization of Dimercury(I) Monofluorophosphate(V),
Hg2PO 3F: Crystal Structure, Thermal Behavior, Vibrational Spectra, and
Solid-State 31P and 19F NMR Spectra. — Single crystals of the title compound are
obtained upon cooling of an aqueous solution of Hg2(NO3)2 and (NH4)2PO3F
(85→20 °C, 24 h). Hg2PO3F crystallizes in the orthorhombic space group Ibam with
Z = 8. The new structure type exhibits H g22 + dumbbells and discrete PO3F2- anions
forming layers. The symmetric H g22 + dumbbell shows a typical Hg—Hg distance of
2.505 Å and the Hg—O distances are found to range from 2.327 to 2.476 Å. No interactions between Hg and F atoms are observed. Hg2PO3F is further characterized by IR
and Raman spectroscopy, thermal analysis (TG, DSC), and 19F and 31P solid-state NMR
spectroscopy. — (WEIL*, M.; PUCHBERGER, M.; BARAN, E. J.; Inorg. Chem. 43
