The chemical composition of the title compound crystal was verified by the analysis of selected single crystals using a field emission scanning electron microscope (JSM-7000F, JEOL, Japan) operating at 15 kV and equipped with a secondary electron detector and a backscatter detector for energy dispersive X-ray spectrometry (EDX) system, INCAx-sight, from Oxford Instruments, UK. The analysis confirmed the presence of all four elements with the atomic ratio (in percentage) Ba:Bi:In:Zn = 33(1):46(1):13(1):8(1), roughly in good agreement with the refined value Ba:Bi:In:Zn = 34.8:43.5:13.9:7.8, and no contaminant was detected.
