The chalcogen-bonding interactions formed at both sides of the thiocarbonyl group in thiourea were investigated. In particular, the role of these chalcogen-bonding interactions in the trans - trans conformation of thiourea was evaluated via single-crystal X-ray diffraction analysis and DFT calculations. The obtained results indicate that the Se⋯S⋯Se dual chalcogen-bonding interactions play a stronger role in controlling the planar structure than the S⋯S⋯S interactions.
