The crystal structure of the title compound, [Zn(C(9)H(7)N(2)O(2))(2)(H(2)O)]·H(2)O, involves discrete mononuclear complex mol-ecules. The special positions on the rotation twofold axis are occupied by Zn(II) and O atoms of the coordinated and uncoordinated water mol-ecules. The coordination around the Zn(II) atom can be described as transitional from trigonal-bipyramidal to square-pyramidal. T...
The title compound, C(17)H(17)N(4) (+)·C(9)H(5)O(6) (-)·C(9)H(6)O(6)·H(2)O, contains a protonated 2,2'-(1,3-propanedi-yl)bis-(1H-benzimidazole) cation, a deprotonated benzene-1,3,5-tricarb-oxy-lic acid anion, a neutral benzene-1,3,5-tricarb-oxy-lic acid mol-ecule and a water mol-ecule, which are linked together through N-H⋯O, O-H⋯O and weak C-H⋯O hydrogen bonds into almost double sheets paralle...
Crystals of the title compound, C14H8Cl6O4S, are twinned by inversion, with unequal components [0.85 (3):0.15 (3)]. The asymmetric unit contains two independent mol-ecules that are related by a pseudo-inversion center. The Car-O [1.393 (9) and 1.397 (9) Å] and ester S-O bond lengths [1.600 (5) and 1.590 (5) Å] of both mol-ecules are comparable to the structurally related 2,3,5,5-trichloro-biphe...
In the title compound, C(14)H(11)ClN(2)O(4)·CH(3)OH, the mol-ecule adopts an E conformation about the C=N bond. The compound is in the enamine-keto form. The two terminal benzene rings make a dihedral angle of 10.53 (9)°. Intra-mol-ecular O-H⋯O and O-H⋯N hydrogen bonding stabilizes the mol-ecular structure. In the crystal, O-H⋯O hydrogen bonds link the mol-ecules, forming chains running along t...
The title compound, C(9)H(8)ClNO(4), crystallizes with two mol-ecules in the asymmetric unit. In each mol-ecule, the carboxyl-ate group is nearly coplanar with the benzene ring, forming dihedral angles of 2.4 (1) and 4.9 (1)°. In the crystal, mol-ecules are linked through weak C-H⋯O and C-H⋯Cl hydrogen bonds. A short O⋯N contact of 2.7660 (19) Å occurs between the nitro groups of adjacent mol-e...
In the title Schiff base mol-ecule, C(13)H(9)BrClN, the dihedral angle between the benzene rings is 49.8 (2)° and the mol-ecule has an E configuration about the C=N bond. In the crystal, there are no directional interactions but only van der Waals inter-molecular inter-action forces between neighbouring mol-ecules.
Mol-ecules of the title compound, [HgBr(C(9)H(11))], are located on a crystallographic twofold rotation axis. Due to the mol-ecular symmetry, the Hg(II) atom is linearly coordinated by the ipso-C of the mesityl group and the Br atom. In the crystal, mol-ecules lie in planes parallel to (001).
In the title compound, 2C(24)H(21)N(3)S·C(6)H(6), the two independent Schiff base mol-ecules (A and B) in the asymmetric unit differ in the orientation of the tetra-hydro-benzothio-phene ring system with respect to the carbazole ring system by 180° rotation about the C-C bond in the C-C=N-C linkage. The two mol-ecules also differ in the orientation of the ethyl groups [C-N-C-C torsion angle of ...
There are two mol-ecules in the asymmetric unit of the title compound, C(15)H(9)Cl(3)O. The fluorene rings of the two mol-ecules are both coplanar within 066 (3) Å. In the crystal, C-H⋯O and C-H⋯Cl hydrogen bonds link the mol-ecules into sheets running parallel to (100).
The title compound, C(11)H(9)N(3)O(4)S, crystallizes with two mol-ecules in the asymmetric unit; each mol-ecule exists as a zwitterion in the solid state. Inter-molecular N-H⋯N hydrogen bonds link the mol-ecules into chains. Weak C-H⋯O inter-actions further stabilize the crystal structure.
