well determined and the main crystallographic data are reported in Table . Even after repeating the synthesis several times and with different methodology, in all the cases we could observe that the racemic material crystallizes in the centrosymmetric P21/c space group with a different stoichiometry with respect to the enantiopure samples, namely (ClMBA)CuCl3. This is not an isolated case and in a recent report about hybrid organic inorganic germanium halides the racemic compound, differently from the enantiopure ones, led to a (rac-NEA)GeI3 (NEA= 1-naphthalen-1-ylethanammonium) stoichiometry. In (ClMBA)CuCl3 the crystal structure is composed of Cu2Cl6 -dimers with five-coordinated Cu(II) ions tied together into infinite chains along the b axis, as depicted in Figures and. The appearance of the crystals is also different compared to the R/S samples (Figure ) and presents a dark brown colour shown in Figure . It is interesting to note that the five coordination for Cu(II) in hybrid organic inorganic copper halides, as found here for (rac-ClMBA)CuCl3, is quite unusual and rarely observed before. Specifically, the other example has been reported in 1965 by Willet for the (CH3)2NH2CuCl3 material crystallizing in the monoclinic I2/a space group and presenting the dimers running along the a axis. The five Cu-Cl bond distances are found to range from 2.2540(13) Å to 2.3200(12) Å, while the bond angles are in the range from about 84.5° to 92.7°, indicating a significant level of distortion of the inorganic framework, significantly higher with respect to the (R/S-ClMBA)2CuCl4
