Phosphoric Triamides

InN,N,N′,N′-tetraethyl-N′′-(4-fluorobenzoyl)phosphoric triamide, C15H25FN3O2P, (I), andN-(2,6-difluorobenzoyl)-N′,N′′-bis(4-methylpiperidin-1-yl)phosphoric triamide, C19H28F2N3O2P, (II), the C—N—C angle at each tertiary N atom is significantly smaller than the two P—N—C angles. For the other new structure,N,N′-dicyclohexyl-N′′-(2-fluorobenzoyl)-N,N′-dimethylphosphoric triamide, C21H33FN3O2P, (III), one C—N—C angle [117.08 (12)°] has a greater value than the related P—N—C angle [115.59 (9)°] at the same N atom. Furthermore, for most of the analogous structures with a [C(=O)NH]P(=O)[N(C)(C)]2skeleton deposited in the Cambridge Structural Database [CSD; Allen (2002).Acta Cryst.B58, 380–388], the C—N—C angle is significantly smaller than the two P—N—C angles; exceptions were found for four structures with theN-methylcyclohexylamide substituent, similar to (III), one structure with the seven-membered cyclic amide azepan-1-yl substituent and one structure with anN-methylbenzylamide substituent. The asymmetric units of (I), (II) and (III) contain one molecule, and in the crystal structures, adjacent molecules are linkedviapairs of N—H...O=P hydrogen bonds to form dimers.
