1,3-Di-n-butyl­thio­urea

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

N-Benzoyl-N′-phenyl­urea

In the title compound, C14H12N2O2, the mol­ecular conformation is determined by a strong intra­molecular N—H⋯O=C hydrogen bond. In the crystal, pairs of mol­ecules are connected by inter­molecular N—H⋯O=C hydrogen bonds, forming centrosymmetric dimers. No specific inter­actions between dimers could be found

Ammonium O,O′-diethyl dithiophosphate

In the title compound, NH4+·(C2H5O)2PS2−, the ammonium cation is connected by four charge-assisted N—H...S hydrogen bonds to four tetrahedral O,O′-diethyl dithiophosphate anions, forming layers parallel to (100). The polar and non-polar constituents of the layers are stacked alternately along [100]. Interlacing of the external ethyl groups through van der Waals interactions combines these layers into a three-dimensional structure

N,N′-Diphenylthiourea acetone monosolvate

In the title compound, C13H12N2S·C3H6O, the phenyl rings of the thiourea molecule are in syn and anti positions in relation to the C=S bond. Two molecules are connected by N—H...S=C hydrogen bonds into a centrosymmetric dimer. An additional N—H...O=C hydrogen bond to the acetone solvent molecule and some weak C—H...π interactions reinforce the crystal structure
