(E)-4-[2-(2-Hy-droxy-benzo-yl)-hydra-zin-ylidene]penta-noic acid.

ABSTRACT: The title mol-ecule, C(12)H(14)N(2)O(4), adopts a trans configuration with respect to the C=N double bond. The amino group is involved in an intra-molecular N-H⋯O hydrogen bond. In the crystal structure, inter-molecular O-H⋯O hydrogen bonds link the mol-ecules into doubled sheets parallel to the (101) plane.

Project description:There are two independent mol-ecules in the asymmetric unit of the title compound, C(23)H(17)N(2)O(4)S, with significant differences in their conformations, e.g. the benzene rings of the benzothia-zine and benzonitrile units are inclined at 28.19?(10) and 17.89?(7)° in the two mol-ecules, with the centroids of the rings separated by 3.975?(2) and 3.637?(2)?Å, respectively. Moreover, the N-C-C-C torsion angles involving the benzoyl group are 14.3?(5) and 8.2?(5)° in the two mol-ecules, showing different degrees of rotation of this group. In both mol-ecules, the heterocyclic thia-zine rings adopt half-chair conformations, with the S and N atoms displaced by 0.427?(6) and 0.365?(6)?Å, respectively, in one mol-ecule and by 0.356?(6) and 0.432?(6)?Å, respectively, in the other, on opposite sides of the mean planes formed by the remaining ring atoms. The crystal structure is stabilized by inter-molecular C-H?O hydrogen bonds and further consolidated by intra-molecular O-H?O hydrogen bonds.

1-(2-Hy-droxy-benzo-yl)thio-semicarbazide hemihydrate.

Project description:The asymmetric unit of the title compound, C(8)H(9)N(3)O(2)S·0.5H(2)O, contains two thiosemicarbazide mol-ecules with the short distance of 3.521?(3)?Å between the centroids of the benzene rings, and one water mol-ecule. In the two independent mol-ecules, the benzene rings and the thio-semicarbazone fragments are twisted at 9.2?(3) and 18.5?(3)°. An extensive three-dimensional hydrogen-bonding network, formed by inter-molecular N-H?O, N-H?S and O-H?O hydrogen bonds, consolidates the crystal packing.

{4-Hy-droxy-N'-[(2E,3Z)-4-oxido-4-phenyl-but-3-en-2-yl-idene]benzo-hydra-zidato}diphenyl-tin(IV) methanol monosolvate.

Project description:Two independent diphenyl-tin mol-ecules and two independent methanol mol-ecules comprise the asymmetric unit of the title compound, [Sn(C(6)H(5))(2)(C(17)H(14)N(2)O(3))]·CH(3)OH. The Sn atom in each is five-coordinated by a tridentate ligand and the ipso-C atoms of the Sn-bound benzene substituents. The resulting C(2)N(2)O donor set defines a coordination geometry that is inter-mediate between trigonal-bipyramidal (TP) and square-pyramidal (SP), with one mol-ecule slightly tending towards TP and the other slightly towards SP. The mol-ecules differ in terms of the relative orientations of the terminal benzene rings [dihedral angles = 45.71 (18) and 53.98 (17)°] and of the Sn-bound benzene substituents [dihedral angles = 59.5 (2) and 45.77 (18)°, respectively]. The most prominent feature of the crystal packing is the formation of four-mol-ecule aggregates via O-H⋯O and O-H⋯N hydrogen bonds, in which the hy-droxy group is connected to a methanol mol-ecule which, in turn, is linked to a non-coordinating N atom. Weak C-H⋯π inter-actions also occur.
