Abstract
The crystal structure of (CH3)2NH2CuCl3 has been determined by x‐ray diffraction techniques. The compound contains approximately planar Cu2Cl6= dimers which contain two bridging chlorine atoms. All Cu–Cl bond distances in the dimer are approximately 2.3 Å and all bond angles approximately 90°. The crystals are pleochroic with maximum visible absorption when the electric vector is parallel to the [301] direction.
