1,3-Di-n-butylthiourea

Abstract

In the title compound, C9H20N2S, the n-butyl groups are in syn and anti positions in relation to the C=S bond. In the crystal, two molecules are connected by two N—H...S=C hydrogen bonds into a centrosymmetric dimer. Another N—H...S=C hydrogen bond links the dimers, forming layers with a hydrophilic interior and a hydrophobic exterior, which spread across the (100) plane. Interlacing of the external butyl groups combines these layers into a three-dimensional structure.
