Hirshfeld surfaces and two-dimensional fingerprint plots are used to visualize and analyze intermolecular interactions in six new phosphoramidate structures, [2,6-F2-C6H3C(O)NH]P(O)[X]2 {X = N(C2H5)2 (1), [X]2 = NHCH2C(CH3)2CH2NH and with one CH3OH solvated molecule (2)}, [C6H5O]2P(O)Y [Y = NC4H8O (3), NHC6H4(3-Br) (4)] and [Z]2P(O)OP(O)[Z]2 [Z =(More)
Phosphoramido acid esters (CH(3))(2)NP(O)X(p-OC(6)H(4)-CH(3)) (containing P-Cl (1), P-O (2), P-F (3), P-CN (5), and P-N (4,6) bonds, X for 2, 4 and 6 is OCH(3), (C(2)H(5))(2)N and morpholin) have been synthesized to investigate the structure-activity study of AChE enzyme inhibition, through the parameters logP, delta(31)P and IC(50). After their(More)
The asymmetric unit of the title compound, C(23)H(28)N(3)OP, contains two independent mol-ecules with significant conformational differences. For example, the torsion angles N-C-C-C involving the N-benzyl moieties are 57.3 (7) and 11.6 (8)° in one mol-ecule and 76.5 (7) and 97.4 (7)° in the other. In each mol-ecule, the P atom exhibits a distorted(More)
In the title compound, C(14)H(18)N(3)OP, a crystallographic mirror plane bis-ects the mol-ecule (the C,N,C atoms of the dimethyl-amido moiety and the P=O unit lie on the mirror plane). The P atom has a distorted tetra-hedral geometry; the bond angles at P are in the range 98.98 (11)-115.28 (7)°. In the crystal, the O atom of the P=O group acts as a double(More)
The phosphoryl and carbonyl groups in the title compound, C(23)H(24)F(2)N(3)O(2)P, are anti to each other. The P atom is in a tetra-hedral coordination environment and the environment of each N atom is essentially planar, the average bond angles at the two N atoms being 119.9 and 119.1°. The H atom of the C(=O)NHP(=O) group is involved in an inter-molecular(More)
The pyridine N atom of the cation in the title hydrated salt, C(13)H(11)N(2) (+)·NO(3) (-)·H(2)O, is protonated; the N atom of the NH(2) group shows a planar conformation. The former N atom is hydrogen bonded to a water mol-ecule. The amino group is involved in three N-H⋯O hydrogen bonds with two neighboring nitrate anions. The water mol-ecule is hydrogen(More)
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(More)
The P atom in the title compound, C(21)H(21)FN(3)O(2)P, is in a tetra-hedral coordination environment and the environment of each N atom is essentially planar (sums of angles = 359.7, 359.9 and 358.4°). The phosphoryl and carbonyl groups adopt anti orientations with respect to each other. In the crystal, adjacent mol-ecules are linked via N-H⋯O=P and two(More)
In the title compound, C(16)H(16)Cl(4)N(3)O(2)P, the phosphoryl and carbonyl groups are anti to each other. The dihedral angle between the benzene rings is 33.59 (16)°. 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.
