ABSTRACT
In the title mol-ecule, C(30)H(30)N(4)S(2), the two benzene rings connected through the disulfide chain form a dihedral angle of 88.7â (1)°, and the two benzene rings in the benzyl-ideneaniline fragments form dihedral angles of 34.0â (1) and 35.4â (1)°. The crystal packing exhibits no significantly short inter-molecular contacts.
ABSTRACT
In the title compound, C(17)H(18)N(4)O(5)·2C(3)H(7)NO, two solvent mol-ecules are linked to the main mol-ecule via N-Hâ¯O and O-Hâ¯O hydrogen bonds, forming a hydrogen-bonded trimer. Intra-molecular O-Hâ¯N hydrogen bonds influence the mol-ecular conformation of the main mol-ecule, and the two benzene rings form a dihedral angle of 10.55â (18)°. In the crystal, inter-molecular O-Hâ¯O hydrogen bonds link hydrogen-bonded trimers into ribbons extending along the b axis.
ABSTRACT
The title compound, 3C(14)H(12)N(2)O(2)·C(3)H(7)NO, was synthesized by reaction of benzoyl chloride with hydrazine hydrate under microwave irradition. The asymmetric unit comprises three 1,2-dibenzoyl-hydrazine mol-ecules and one dimethyl-formamide mol-ecule. The 1,2-dibenzoyl-hydrazine mol-ecules are linked by pairs of N-Hâ¯O hydrogen bonds into chains propagating along [010].
ABSTRACT
In the title mol-ecule, C(18)H(21)ClN(2)O(3)S, the pyrimidine ring exhibits a half-chair conformation. The ethyl group is disordered between two positions in a ratio 0.74:0.26. In the crystal structure, the mol-ecules are linked into chains along the a axis by N-Hâ¯O hydrogen bonds.
ABSTRACT
The asymmetric unit of the title compound, C(23)H(18)Br(2)O(2), contains two independent mol-ecules with slightly different conformations. In the absence of classical inter-molecular inter-actions, the crystal packing is stabilized by van der Waals forces.
ABSTRACT
The asymmetric unit of the title compound, C(19)H(16)O(2)S(2), contains two independent mol-ecules with slightly different conformations. In the crystal structure, weak inter-molecular C-Hâ¯O hydrogen bonds [Câ¯O = 3.279â (15) and 3.407â (16)â Å] link the mol-ecules into chains extended along the c axis.
ABSTRACT
The asymmetric unit of the title compound, C(25)H(25)NO(2), contains two independent mol-ecules. The crystal packing exhibits weak inter-molecular C-Hâ¯O, C-Hâ¯π and π-π inter-actions.
