N-[4-Chloro-2-(2-chlorobenzoyl)phenyl]acetamide
In the title compound, C(15)H(11)Cl(2)NO(2), the dihedral angle between the two benzene rings is 74.83 (5)°. The N-bound and terminal benzene rings are inclined at dihedral angles of 4.09 (10) and 78.38 (9)°, respectively, to the mean plane through the acetamide group. Intra-molecular C-H⋯O and N-H⋯O hydrogen bonds both generate S(6) rings.

متن کاملResolvable packings R̃ MP ( 3 , 2 ; n , n − 3 ) and coverings R̃ MC ( 3 , 2 ; n , n − 2 )
Letn ≡ k−1, 0 or 1 (mod k).An R̃MP(k, ; n,m) (resp. R̃MC(k, ; n,m)) is a resolvable packing (resp. covering)withmaximum (resp. minimum) possible number m of parallel classes which are mutually distinct, each parallel class consists of (n− k + 1)/k blocks of size k and one block of size n− k (n− k+ 1)/k , and its leave (resp. excess) is a simple graph. Such designs can be used to construct certain...
متن کاملN-(2-Chlorobenzoyl)-N′-(3-pyridyl)thiourea
In the mol-ecule of the title compound, C(13)H(10)ClN(3)OS, the dihedral angles between the plane through the thio-urea group and the pyridine and benzene rings are 53.08 (3) and 87.12 (3)°, respectively. The mol-ecules are linked by inter-molecular N-H⋯N hydrogen-bonding inter-actions to form a supra-molecular chain structure along the a axis. An intra-mol-ecular N-H⋯O hydrogen bond is also pr...
متن کاملN′-(3-Methylquinoxalin-2-yl)-N′-phenylbenzohydrazide
In the crystal structure of the title compound, C(22)H(18)N(4)O, the quinoxaline system makes dihedral angles of 86.59 (7) and 63.37 (9)° with the benzohydrazide and phenyl rings, respectively. The benzohydrazide ring makes a dihedral angle of 72.46 (10)° with the phenyl ring. The crystal structure is stabilized by inter-molecular N-H⋯O hydrogen bonds, C-H⋯O contacts and C-H⋯π inter-actions.
