We propose to measure the same single crystal sample of three compounds that emphasize different aspects of structure analysis of neutron SCD data:1. Natrolite (Na2 Al2 Si3 O10 × 2H2O, space group Fdd2, unit cell a = 18.2859 Å, b = 18.6117 Å, c = 6.5870 Å, a = 90 °, b = 90 °, g = 90 °) of the zeolite family is an alumo-silicate with porous 3D framework allowing framework distortion and resulting in negative thermal expansion. Due to this property it is industrially exploitable. The framework is rigid enough to be stable over a wide range of temperatures and pressures. The cavities are filled with one sodium and two waters.2. Lithium ammonium tartrate (LiNH4C4H406 × H20, space group P21212, a = 7.884 Å, b = 14.565 Å, c = 6.409 Å, a = 90 °, b = 90 °, g = 90 °) is a non centro-symmetric molecular material.3. Olivine, Li(Fe/Mn)PO4 synthesized to specific composition, a material of interest for energy material research and battery materials.Each of the chosen crystal will be measured on D19 and D9 to the highest reasonably attainable accuracy (residuals 1 to 3% expected) and d-spacing resolution.
