10-(2-Eth-oxy-1,3-thia-zol-5-yl)-10-hy-droxy-phenanthren-9(10H)-one.

ABSTRACT: In the title compound, C(19)H(15)NO(3)S, the dihydro-phenanthrene unit is not planar, its central ring being distorted towards a sofa conformation. The essentially planar thia-zole ring [maximum deviation = 0.005?(1)?Å] is inclined at a dihedral angle of 85.29?(5)° with respect to the mean plane formed through the dihydro-phenanthrene unit. In the crystal structure, pairs of inter-molecular C-H?O hydrogen bonds link adjacent mol-ecules into inversion dimers. Inter-molecular O-H?N hydrogen bonds further inter-connect these dimers into chains along the a axis. The crystal structure is further stabilized by weak inter-molecular C-H?? inter-actions involving the thia-zole ring.

tert-But-yl(2-hy-droxy-eth-yl)aza-nium 4-[(1,3-thia-zol-2-yl-aza-nid-yl)sulfon-yl]aniline.

Project description:Two pairs of independent cations and anions comprise the asymmetric unit of the title salt, C(6)H(16)NO(+)·C(9)H(8)N(3)O(2)S(2) (-). The cations are virtually superimposable and each exhibits a gauche disposition of the hy-droxy O and ammonium N atoms [the O-C-C-N torsion angles are 55.5 (3) and 57.5 (3)°]. Significant differences are seen in the mol-ecular structures of the anions as seen in the S-N-C-S [1.1 (3) and 32.9 (3)°] and C-S-N-C [-69.7 (2) and 91.4 (2)°] torsion angles. Despite the variations in conformation, intra-molecular hypervalent S⋯O inter-actions persist in each anion [3.078 (2) and 2.8730 (19) Å]. In the crystal, supra-molecular double layers are formed in the bc plane, being sustained by O-H⋯N, N-H⋯O and N-H⋯N hydrogen bonding. These are connected along the a axis via C-H⋯O inter-actions.

Tautomerism in 10-(hy-droxy-imino)-phenanthren-9-one.

Project description:In the title compound, C(14)H(9)NO(2), a static disorder exists between the keto-oxime and hy-droxy-nitroso tautomers, in an approximate ratio of 4.6:1, based on refined occupancies for disordered parts. No inter-molecular hydrogen bonding is present in the crystal structure. Instead, both tautomers exhibit similar intra-molecular O-H?O hydrogen bonds.

(Z)-3-(2-Hy-droxy-eth-yl)-2-(phenyl-imino)-1,3-thia-zolidin-4-one.

Project description:In the title compound, C(11)H(12)N(2)O(2)S, the thia-zole and phenyl rings are inclined at 56.99 (6)° to one another. The thia-zole ring is planar with an r.m.s. deviation for the five ring atoms of 0.0274 Å. The presence of the phenyl-imine substituent is confirmed with the C=N distance to the thia-zole ring of 1.2638 (19) Å. The mol-ecule adopts a Z conformation with respect to this bond. The -OH group of the hy-droxy-ethyl substituent is disordered over two positions with relative occupancies 0.517 (4) and 0.483 (4). In the crystal, O-H⋯O hydrogen bonds, augmented by C-H⋯N contacts, form dimers with R(2) (2)(11) rings and generate chains along the b axis. Parallel chains are linked in an obverse fashion by weak C-H⋯S hydrogen bonds. C-H⋯O hydrogen bonds together with C-H⋯π contacts further consolidate the structure, stacking mol-ecules along the b axis.

4-(2-Hy-droxy-eth-oxy)phenol.

Project description:The asymmetric unit of the title compound, C8H10O3, contains four mol-ecules, which differ in the orientation of the hy--droxy-ethyl group [O-C-C-O torsion angles = -168.89?(17), 72.9?(2), -65.8?(2) and 71.8?(2)°], as well as the orientation of the hy-droxy H atoms. Furthermore, the crystal structure displays two different types of strong hydrogen bond. The first is between an alcohol O-H and another alcohol O atom, and the second between an alcohol O-H group and an ether O atom. Additional weak hydrogen bonds between C-H groups and ether O atoms stabilize the structure.

2-[7-(3,5-Dibromo-2-hy-droxy-phen-yl)-6-eth-oxy-carbonyl-2-oxo-5H-2,3,6,7-tetra-hydro-thio-pyrano[2,3-d][1,3]thia-zol-6-yl]acetic acid ethanol monosolvate.

Project description:The title compound, C(17)H(15)Br(2)NO(6)S(2)·C(2)H(5)OH, is the esterification reaction product of 2-(8,10-dibromo-2,6-dioxo-3,5,5a,11b-tetra-hydro-2H,6H-chromeno[4',3':4,5]thio-pyrano[2,3-d]thia-zol-5a-yl)acetic acid. Cleavage of the lactone ring and formation of eth-oxy-carbonyl and hy-droxy groups from its structural elements were observed. On the other hand, the carb-oxy-methyl group was not esterified. The H atom and carb-oxy-methyl group, both at stereogenic centres, show a cis conformation. The six-membered dihydro-thio-pyran ring adopts a half-chair conformation. All NH and OH groups participate in the three-dimensional hydrogen-bond network, which is additionally strengthened by C-H?O and C-H?S inter-actions. Intramolecular O-H?Br and C-H?O interactions also occur.

(E)-5-[(3-Eth-oxy-2-hy-droxy-benzyl-idene)amino]-1,3,4-thia-diazole-2(3H)-thione.

Project description:In the title compound, C(11)H(11)N(3)O(2)S(2), the dihedral angle between the benzene ring and the five-membered ring is 6.85?(9)°. An intra-molecular O-H?N hydrogen bond makes an S(6) ring motif. In the crystal, mol-ecules are linked through bifurcated N-H?(O,O) hydrogen bonds with R(1) (2)(5) ring motifs, forming chains along the b axis. A short C?S contact [3.3189?(19)?Å], which is shorter than the sum of the van der Waals radii of these atoms (3.50?Å), occurs in the structure. The crystal structure is further stabilized by C-H?N hydrogen bonding and ?-? inter-actions [centroid-centroid distance = 3.7649?(12)?Å].
