N-[Bis(morpholin-4-yl)phosphinoyl]-2-chloro-2,2-difluoroacetamide
The asymmetric unit of the title compound, C10H17ClF2N3O4P, consists of two independent molecules in each of which the P atom adopts a distorted tetrahedral environment with the P=O and N—H units in a syn orientation with respect to one another. Both morpholine rings in one of the phosphoramide molecules are disordered over two sets of sites, with site occupancies of 0.766 (7) and 0.234 (7) for one ring and 0.639 (10) and 0.361 (10) for the other. In the second phosphoramide molecule, one of the NC4H8O moieties is disordered over two sets of sites with site occupancies of 0.807 (6) and 0.193 (6). In the crystal, pairs of intermolecular N—H⋯O(P) hydrogen bonds form two independent centrosymmetric dimers
Monoclinic modification of N-benzylpropan-2-aminium chloride
In the title salt, C10H16N+·Cl−, the cations and anions are linked by two N—H⋯Cl hydrogen bonds, forming a centrosymmetric tetramer
N,N′-Dicyclohexyl-N′′-(4-nitrobenzoyl)phosphoric triamide
The P atom in the title compound, C19H29N4O4P, exhibits a tetrahedral coordination and the phosphoryl and carbonyl groups are anti to each other. Adjacent molecules are linked by N—H⋯O hydrogen bonds to form a layer motif
N,N′-Dibenzyl-N′′-(2-chloroacetyl)-N,N′-dimethylphosphoric triamide
In the title molecule, C18H23ClN3O2P, the P atom is bonded in a distorted tetrahedral environment. The P=O and N—H groups are syn with respect to each other. The angles at the tertiary N atoms confirm their sp
2 character. In the crystal, pairs of intermolecular P=O⋯H—N hydrogen bonds form centrosymmetric dimers
Diphenyl (2-chlorobenzylamido)phosphate
In the title compound, C19H17ClNO3P, the P atom exhibits a distorted tetrahedral configuration. In the crystal, pairs of intermolecular N—H⋯O(P) hydrogen bonds form centrosymmetric dimers
N,N′-Bis(2-methylphenyl)-N′′-(2,2,2-trichloroacetyl)phosphoric triamide
In the title compound, C16H17Cl3N3O2P, the P—N bonds in the P(O)[NH(2—CH3)C6H4]2 unit [1.623 (4) and 1.637 (3) Å] are shorter than the P—N bond in the C(O)NHP(O) fragment [1.704 (3) Å]. The phosphoryl and carbonyl groups are anti with respect to each other and the P atom has a distorted tetrahedral configuration. In the crystal, adjacent molecules are linked via N—H⋯O(P) and N—H⋯O(C) hydrogen bonds into an extended chain parallel to [101]
N-Cyclohexylcyclohexanaminium chloride
In the title salt, C12H24N+·Cl−, both cyclohexyl rings adopt chair conformations and the NH2 unit is situated in the equatorial position with respect to the rings in the cation. The large C—N—C bond angle [117.99 (14)°] in the cation is a result of linking two bulky cyclohexyl rings to the N atom. The aminium H atoms are involved in intermolecular N—H⋯Cl hydrogen bonds, forming an infinite zigzag chain parallel to the c axis. The crystal studied was a racemic twin with a twin fraction of 0.28 (18)
N,N′-Bis(2-chlorobenzyl)-N′′-(2,2,2-trichloroacetyl)phosphoric triamide
The P atom in the title compound, C16H15Cl5N3O2P, exhibits a tetrahedral coordination geometry and the phosphoryl and carbonyl groups are anti with respect to one another. The dihedral angle between the benzene rings is 44.90 (15)°. One of the 2-chlorobenzylamido fragments is disordered over two sets of sites with occupancies of 0.8823 (17) and 0.1177 (17). In the crystal, adjacent molecules are linked via N—H⋯O(P) and N—H⋯O(C) hydrogen bonds into an extended chain running parallel to the a axis
Diphenyl (o-tolylamido)phosphonate
The asymmetric unit of the title compound, C19H18NO3P, contains two independent molecules in which the P atoms are found in slightly distorted tetrahedral environments. In the crystal, pairs of intermolecular N—H⋯O(P) hydrogen bonds form two independent centrosymmetric dimers
N,N′-Dicyclohexyl-N′′-(3-fluorobenzoyl)-N,N′-dimethylphosphoric triamide
In the title compound, C21H33FN3O2P, the P atom has a distorted tetrahedral environment and the N atoms display geometries consistent with a model of sp
2 hybridization (with bond-angle sums for the tertiary N atoms of 357.8 and 358.7°). The phosphoryl and carbonyl groups are anti with respect to each other. In the crystal, inversion dimers linked by pairs of N—H⋯O hydrogen bonds generate R
