N,N'-Bis(4-methyl-phen-yl)-N''-(2,2,2-trichloro-acet-yl)phospho-ric triamide.

The P atom in the title compound, C(16)H(17)Cl(3)N(3)O(2)P, is bonded in a distorted tetra-hedral geometry with the phosphoryl and carbonyl groups anti with respect to one another. In the crystal, mol-ecules are linked through (N-H)(2)⋯O(=P) and N-H⋯O(=C) hydrogen bonds into chains along [001]. The phosphoryl O atom acts as a double hydrogen-bond acceptor.

N,N'-Bis(2-chloro-benz-yl)-N''-(2,2,2-trichloro-acet-yl)phospho-ric triamide.

The P atom in the title compound, C(16)H(15)Cl(5)N(3)O(2)P, exhibits a tetra-hedral 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-chloro-benzyl-amido fragments is disordered over two sets of sites with occupancies of 0.8823 (17) and 0.1177 (17). In the crystal, adjacent mol-ecules are linked via N-H⋯O(P) and N-H⋯O(C) hydrogen bonds into an extended chain running parallel to the a axis.

Cyclo-hex-yl(meth-yl)ammonium {bis-[cyclo-hex-yl(meth-yl)amino]-phosphor-yl}(4-methyl-phenyl-sulfon-yl)aza-nide.

In the anion of the title salt, C(7)H(16)N(+)·C(21)H(35)N(3)O(3)PS(-), the P and S atoms are both in distorted tetra-hedral environments and the angles at the tertiary N atoms confirm their sp(2) character. The two S=O groups are in syn and gauche conformations with respect to the phosphoryl group. In the crystal, N-H⋯O(=S) and N-H⋯O(=P) hydrogen bonds involving two anions and two cations form a centrosymmetric four-component cluster.
