چکیده
The title compound, C(15)H(13)ClN(2)O(3)S, is one of a series of N(1)-benzyl-1,3-dihydro-2H-benzimidazol-2-one derivatives, a new class of non-nucleoside HIV-1 reverse transcriptase inhibitors. The dihedral angle between the two pharmacophoric groups, the dimethyl-benzene ring and the benzimidazolone ring system, is 88 (1)°, giving a butterfly-like conformation to the mol-ecule. The mol-ecular packing is characterized by a bifurcated N-H⋯(O,O) hydrogen bond and short Cl⋯O contacts of 3.122 (2) Å. In addition, π-π stacking of the benzimidazolone rings is also present, with inter-planar separations of 3.95 (1) Å.

In the reaction of 7-chloro-1,5-benzodiazepine-2,4-dione with N,N-dimethyl-formamide/dimethyl-acetal, the diazepine seven-membered ring undergoes a contraction to form the five-membered ring. The reaction yields two isomers the title compound, C(13)H(14)ClN(3)O(2); the major component has the chlorine-atom substituent in the 5-position of the benzimidazolone ring and the minor component has the...

In the title complex, [Zn(C(9)H(5)O(6))(2)(C(11)H(10)N(4))(2)]·8H(2)O, the Zn(II) ion exhibits site symmetry 2. It shows a distorted tetra-hedral coordination defined by two N atoms from two symmetry-related 1-[(1H-benzimidazol-2-yl)meth-yl]-1H-imid-azole ligands and by two O atoms from two symmetry-related monodeprotonated 3,5-dicarb-oxy-benzoate anions. In the crystal, complex mol-ecules and ...
