- Abstract
- The reaction between 4-(dimethylamino)aniline and O,O′-diisopropyl- isothiocyanatothiophosphoric acid (iPrO) 2P(S)NCS gives the N-thiophosphorylated thiourea 4-Me 2NC 6H 4NHC(S)NHP(S)(OiPr) 2 (L). The structure of this compound was investigated by IR, 1H, 31P{ 1H} NMR spectroscopy; its composition was examined by microanalysis. Recrystallization of L from an acetone/n-hexane mixture leads to the formation of the triclinic polymorph L1 with cell parameters a = 7.6486(2), b = 9.8087(13), c = 13.7522(14) Å, α = 79.685(10), β = 84.090(7), γ = 70.463(8)°, V = 955.58(17) Å 3, and Z = 2. Recrystallization of L from a CH 2Cl 2/n-hexane mixture leads to the formation of the triclinic polymorph L2 with cell parameters a = 10.2581(6), b = 13.1606(7), c = 14.9343(8) Å, α = 90.718(3), β = 107.751(3), γ = 93.285(2)°, V = 1916.07(18) Å 3, and Z = 4. © 2012 Elsevier B.V.
