Magnetic reflections, as indexed in the plot, were observed at 1 K. No trace of any magnetic reflection was observed at 9 K. Contrary to previous neutron diffraction study, magnetic reflections have been observed by us in Clinoatacamite at 9 K (22). Considering the similar XRD patterns of Clinoatacamite and triclinic Cu4(OH)6Cl2, which are almost undistinguishable at low diffraction angles, as well as the revealed magnetic properties in this work, we have sufficient reason to suspect that the previous neutron study (15) intended for the intermediate TN2 < T < TN1 phase of Clinoatacamite might be actually done on a wrongly identified triclinic Cu4(OD)6Cl2. Source data are provided as a Source Data file.
