Abstract:
The authors of a recent paper (Optik 127 (2016) 3582-3589) report to have grown a so called bis (thiourea) strontium chloride (BTSC) and claim it to be a potential optoelectronic material. In this comment it is shown that this claim is dubious and BTSC reported once earlier by Hajiyani et al. (Mod. Phys. Lett. B, 21 (2010) 735-747) is actually thiourea.
