N,N'-Dicyclo-hexyl-N,N'-dimethyl-N''-(4-nitro-benzo-yl)phospho-ric triamide.

ABSTRACT: The P atom in the title compound, C(21)H(33)N(4)O(4)P, is in a slightly distorted tetra-hedral coordination environment and the phosphoryl and carbonyl groups are anti to each other. The environment of each N atom is essentially planar (average angles of 119.9 and 118.4°). In the crystal structure, the H atom of the C(=O)NHP(=O) group is involved in an inter-molecular -P=O⋯H-N- hydrogen bond, forming centrosymmetric dimers.

N,N'-Dicyclo-hexyl-N''-(2,6-difluoro-benzo-yl)-N,N'-dimethyl-phospho-ric triamide.

Project description:In the title mol-ecule, C(21)H(32)F(2)N(3)O(2)P, the P=O and N-H groups are syn with respect to each other, and the P atom is bonded in a distorted tetra-hedral environment. The phosphoryl group adopts an anti orientation with respect to the carbonyl group. The angles at the tertiary N atoms (with bond-angle sums of 358.4 and 357.0°) confirm their sp(2) character. In the crystal, inversion dimers linked by pairs of N-H?O hydrogen bonds generate R(2) (2)(8) loops.

N,N'-Dicyclo-hexyl-N'',N''-dimethyl-phospho-ric triamide.

Project description:In the title compound, C(14)H(30)N(3)OP, both cyclo-hexyl groups adopt chair conformations with the NH unit in an equatorial position. The P atom adopts a slightly distorted tetra-hedral environment. In the (CH(3))(2)NP(O) unit, the O-P-N-C torsion angles, showing the orientations of the methyl groups with respect to the phosphoryl group, are -166.6?(3) and 34.6?(4)°. The O atom of the P=O group acts as a double hydrogen-bond acceptor and is involved in two different inter-molecular N-H?OP hydrogen bonds, building R(2) (2)(8) rings that are further linked into chains running parallel to the b axis.

Project description:In the title compound, C(21)H(33)FN(3)O(2)P, the P atom has a distorted tetra-hedral 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.

N-Benzoyl-N',N''-dicyclo-hexyl-phospho-ric triamide.

Project description:In the title compound, C(19)H(30)N(3)O(2)P, the central P atom has a distorted tetra-hedral configuration. The N atoms in both cyclo-hexyl-amide moieties exhibit a slight deviation [0.32?(7) and 0.44?(6)?Å] from planarity, while the benzoyl-amide N atom is planar [0.11?(3)?Å]. In the crystal, mol-ecules are linked via N-H?O(P) and N-H?O(C) hydrogen bonds, forming R(2) (2)(10) rings within linear arrangements parallel to the b axis.

N,N'-Dicyclo-pentyl-N'',N''-dimethyl-phospho-ric triamide.

Project description:The P atom in the title mol-ecule, C(12)H(26)N(3)OP, has a distorted tetra-hedral configuration: its bond angles lie in the range 101.1?(2)-119.1?(2)°. The P-N bonds to the two cyclo-pentyl-amido moieties are significantly different [1.619?(4) and 1.643?(4)?Å], with the shorter bond related to an anti orientation of the lone electron pair of the corresponding N atom relative to the P=O bond. The O atom of the P=O group acts as a double hydrogen-bond acceptor and is involved in two different inter-molecular N-H?O(P) hydrogen bonds, building R(2) (2)(8) rings that are further linked into chains along [001].

Project description:In the title mol-ecule, C(23)H(24)F(2)N(3)O(2)P, the P atom is in a distorted tetra-hedral P(=O)(N)(N)(2) environment, with the bond angles around the P atom in the range 106.78 (11)-114.10 (13)°.

The N atoms have sp(2) character. In the crystal, pairs of P=O⋯H-N hydrogen bonds form inversion dimers with R(2) (2)(8) ring motifs.
