Abstract
Abstract Thiocarbamoyl phosphonates, (RO)2PO[sbnd]CS[sbnd]NHR, which are crystalline solids, were shown by X-ray crystallography to be associated in dimers. These dimers are held by two P=O … H[sbnd]N bonds forming a ten-membered planar ring. In crystals of compounds containing an N-benzyl group, the aromatic rings are arranged symmetrically above and below the ten-membered ring. Thiophosphoryl analogs, (RO)2 PS[sbnd]CS[sbnd]NHR, do not seem to contain any hydrogen bonds in their crystals, thus explaining the fact that most of these compounds are liquids at room temperature. The findings seem to reinforce a previous argument that the different nmr behavior of compounds of the two sets, when dissolved in benzene, is due to the association of molecules of the phosphoryl series, through hydrogen bonding, in non-polar solvents.
