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

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′-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

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)

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 2 2(8) loops
