The authors of the title paper ( Cryst. Res. Technol . 2018 , 53 , 1700271) report to have grown a new nonlinear optical sodium cadmium tetra chloride (SCTC) single crystal by slow evaporation from an aqueous solution. A critical analysis of the title paper proves that the so‐called SCTC crystal is an improperly characterized material. Taking the title crystal as an example, it is suggested that submission of CIF file to a database be made an essential prerequisite for journal publication of new compounds.
