Structure and disorder in schultenite, lead hydrogen arsenate

  title={Structure and disorder in schultenite, lead hydrogen arsenate},
  author={Chick C. Wilson and Philip J. Cox and Neil S. Stewart},
  journal={Journal of Crystallographic and Spectroscopic Research},
The structure of lead hydrogen arsenate has been studied by pulsed neutron single crystal diffraction. The structural parameters obtained agree well with the best available X-ray data. In addition, the hydrogen atom positions and disorder have been well characterized, yielding potentially important information regarding hydrogen atom potentials.

Abstract The structure of the mineral schultenite, PbHAsO4, has been studied using pulsed neutron single crystal diffraction. The low-temperature, low-symmetry structure is found to exhibit


This review is the last of three reviews covering the structures of lead compounds, and covers over two hundred lead oxoacids and halides, only fourteen of which have the lead atom in its +4

Macroscopic and structural effects of hydrogen-bond transformations

A brief account of transformations of internal structure of hydrogen bonds, and transformations involving the breaking and formation of hydrogen bonds is highlighted for a selected group of crystals.

Parageneses and Crystal Chemistry of Arsenic Minerals

The labyrinthine world of arsenic minerals has piqued the curiosity of many researchers in mineralogy, geochemistry, chemistry, and environmental sciences. Arsenic was known to the ancient



CORRIGENDUM: On the pressure dependence of the crystal structure of PbHPO4

The room-temperature crystal structure of LbHPO4 has been determined by neutron diffraction at 1.5 GPa. Under these conditions, PbHPO4 is in its high-temperature, disordered phase. The principal

On the structural evidence for a direct proton tunnelling effect in the KH2PO4-type transition

High-resolution neutron diffraction results for KH2PO4 (KDP) and its deuterated form (DKDP) have been used to re-examine evidence that the large increase in the phase transition temperature, Tc, on

Dynamics and statics of the ferroelectric phase transition in PbHPO4

The Raman spectrum of PbHPO4 has been studied as a function of temperature between 10 and 320K (Tc approximately=310K). A soft-mode is observed whose frequency has a temperature dependence that is

Ferroelectricity in lead monohydrogen phosphate, PbHPO4, and the deuterated form, PbDPO4

PbHPO4 and the deuterated form PbDPO4 are found to be ferroelectric at room temperature with space group Pc. Pyroelectric, dielectric and ferroelectric measurements as a function of temperature show
