摘要

We performed powder neutron diffraction experiments at T = 2.5 K on partially deuterated L-tartrate copper tetrahydrate, a magnetic material with a chiral crystal structure. Rietveld refinement of the powder neutron diffraction patterns enabled the determination of hydrogen (deuterium) atom positions within the one-dimensional hydrogen-bonding network previously reported in the literature (Rashidipour et al. in Arab J Chem 10:S3167, 2017). Additionally, we measured the temperature dependence of the magnetic susceptibility from 2 to 300 K for both deuterated and non-deuterated L-tartrate copper samples. Analysis using a model with two types of one-dimensional chains showed that the effect of deuteration on magnetic properties is minimal within the measured temperature range.
