Muhammad Nadeem Arshad,Muhammad Danish,Muhammad Nawaz Tahir,Savera Khalid
Acta Crystallographica Section E , 2012, DOI: 10.1107/s1600536812033260
Abstract: In the title compound, C12H16N2O6S, the S atom adopts a distorted tetrahedral geometry with an O—S—O angle of 119.76 (13)°. The nitro group is twisted by 35.34 (2)° with respect to the aromatic ring; it accepts an N—H...O hydrogen bond, resulting in a S(7) motif. In the crystal, N—H...O and O—H...O hydrogen bonds connect the molecules into an infinite chain along the a axis. The methyl C atoms of the isopropyl group are disordered in a 1:1 ratio.

Abstract: In the title complex, [HgBr2(C12H11NO3)], the HgII ion has a distorted core trigonal–planar geometry comprising two Br atoms and one quinoline N atom of the methyl 2-(quinolin-8-yloxy)acetic acid ligand. The angles around the Hg atom vary from 100.31 (15) to 152.65 (4)°. Two additional Hg...O interactions [2.739 (1) and 2.905 (1) ] complete the coordination sphere about the HgII atom.
2-(5-Cyclohexyl-3-methylsulfanyl-1-benzofuran-2-yl)acetic acid

Acta Crystallographica Section E , 2011, DOI: 10.1107/s1600536811026298
Abstract: In the title compound, C17H20O3S, the cyclohexyl ring adopts a chair conformation. In the crystal, the carboxyl groups are involved in intermolecular O—H...O hydrogen bonds, which link the molecules into centrosymmetric dimers. These dimers are further stabilized by weak intermolecular C—H...O hydrogen bonds. In addition, the crystal structure also exhibits aromatic π–π interactions between the furan rings of adjacent molecules [centroid–centroid distance = 3.505 (2) , interplanar distance = 3.385 (2) and slippage = 0.909 (2) ], and intermolecular C—H...π interactions.
LIQUID-LIQUID EQUILIBRIA OF THE ACETIC ACID-WATER-MIXED SOLVENT (CYCLOHEXYL ACETATE-CYCLOHEXANOL) SYSTEM
?ehreli, S.;
Brazilian Journal of Chemical Engineering , 2002, DOI: 10.1590/S0104-66322002000100004
Abstract: mixtures of cyclohexyl acetate and cyclohexanol were used as a mixed solvent to study liquid-liquid equilibria (lle) of the acetic acid-water-cyclohexanol-cyclohexyl acetate quaternary system. the solubility diagram and tie-line data were determined at 298±0.20 k and atmospheric pressure, using various compositions of mixed solvent. reliability of the data was ascertained by making othmer-tobias and hand plots.

Acta Crystallographica Section E , 2012, DOI: 10.1107/s1600536812028735
Abstract: In the title compound, C16H14N2O4, the dihedral angle between the aromatic rings is 12.45 (6)°. The central C(=O)—N—N=C bridge is roughly planar (r.m.s. deviation = 0.0346 ) and makes dihedral angles of 13.01 (7) and 0.56 (7)° with the attached phenyl and benzene rings, respectively. The acetic acid unit (r.m.s. deviation = 0.0066 ) is twisted from its attached benzene ring [dihedral angle = 19.48 (6)°]. In the crystal, molecules are linked by O—H...(O,N), N—H...O and C—H...O hydrogen bonds into sheets lying parallel to the bc plane. A weak aromatic π–π stacking interaction is also observed [centroid–centroid distance = 3.7330 (7) ].
