Abstract: In the title compound, [Hg(CN)₂(C₉H₂₀N₂S)₂], the Hg atom lies on a twofold rotation axis. There is only half a molecule in the asymmetric unit. The Hg atom has a distorted tetrahedral coordination involving the S atoms of two 1-butyl-3-propylthiourea groups and the C atoms of the two CN^- anions. In the crystal packing, adjacent molecules are connected by intermolecular N-HN and N-HS hydrogen bonds, forming infinite chains in three dimensions.
