Project description:There is one half-mol-ecule in the asymmetric unit of the title compound, C(16)H(14)Cl(2)N(2)O(2), with a center of symmetry at the mid-point of the central C-C bond. The N-H and C=O bonds in the C-NH-C(O)-C fragment are anti to each other and the amide O atom is anti to the H atoms attached to the adjacent C atoms. However, the conformation of the N-H bond in the amide fragments is syn to the ortho-chloro groups in the adjacent benzene rings. The dihedral angle between the benzene ring and the NH-C(O)-CH(2) fragment is 47.0?(2)°. In the crystal, a series of N-H?O inter-molecular hydrogen bonds link the mol-ecules into chains along the b axis.

N-(2-Chloro-phen-yl)-N'-(2-methyl-phen-yl)succinamide.

Project description:In the title compound, C(17)H(17)ClN(2)O(2), the asymmetric unit contains half a mol-ecule with a centre of symmetry at the mid-point of the central C-C bond. The conformations of the amide O atoms are anti to the methyl-ene atoms. Further, the N-H bonds in the amide fragments are anti to the ortho-chloro/methyl groups in the adjacent benzene rings. The dihedral angle between the benzene ring and the NH-C(O)-CH(2) segment in the two halves of the mol-ecule is 62.0?(2)°. In the crystal, a series of N-H?O inter-molecular hydrogen bonds link the mol-ecules into column-like infinite chains along the a axis. The methyl and Cl groups are disordered with respect to the ortho positions of the benzene ring, with site-occupation factors of 0.5 each.

Project description:The asymmetric unit of the title compound, C(17)H(17)ClN(2)O(2), contains one half-mol-ecule with a center of inversion at the mid-point of the central C-C bond. The amide N-H group is anti to the meta-chloro/methyl groups in the adjacent benzene rings. The dihedral angle between the benzene ring and the NH-C(O)-CH(2) segment is 43.5?(1)°. In the crystal, inter-molecular N-H?O hydrogen bonds link the mol-ecules into chains along the a axis. The methyl group and the Cl atom occupy the same position and were treated in a disorder model with site-occupation factors of 0.5 each.

Project description:The asymmetric unit of the title compound, C(18)H(20)N(2)O(2)·2H(2)O, contains half a mol-ecule with a center of symmetry at the mid-point of the central C-C bond.
