Abstract
New powder X-ray diffraction data of davyne, a member of the cancrinite group of minerals, were collected using a rotating anode diffractometer: the hexagonal cell parameters are a = 12.6711(3) Å, c = 5.3278(2) Å, volume 740.82(4) Å3 (space group P63). The strongest lines are: 3.658(100), 4.790(73), 3.272(70), 2.112(48), 2.438(22), 2.663(19), 1.781(19), and 4.147(17). The new data provide quantitative intensities improved precision in rf-spacings and cover an increased 2 θ angular range with respect to PDF 20-379. Measured intensities and a simulated pattern are reported together with crystal-chemical considerations.
