چکیده
The title compound, C(11)H(14)O(3), is a multiple-substituted derivative of benzoic acid. Intra-cyclic C-C-C angles span a range of 117.16 (19)-122.32 (19)°. Apart from intra-molecular hydrogen bonds between hydroxyl and carboxyl groups, inter-molecular hydrogen bonds are present in the crystal structure, the latter ones giving rise to centrosymmetric carb-oxy-lic acid dimers.

The title compound, C(12)H(14)O(6), a substituted isophthalic acid monoester which was isolated from the lichen Thamnolia vermicularis var. subuliformis, displays intra-molecular carbox-yl-meth-oxy O-H⋯O and hy-droxy-carboxyl O-H⋯O hydrogen-bonding inter-actions. The terminal methyl group of the ethyl ester is disordered over two sets of sites with occupancies of 0.599 (19) and 0.401 (19).

In the title compound, [Ni(C(6)H(6)N(4))(2)(H(2)O)(2)](C(8)H(7)O(2))(2)·2C(8)H(8)O(2), the Ni(II) atom (site symmetry ) is coordinated by two N,N'-bidentate 2,2'-biimidazole ligands and two water mol-ecules, resulting in a slightly distorted trans-NiO(2)N(4) geometry for the metal ion. In the crystal, the components are linked by N-H⋯O and O-H⋯O hydrogen bonds, generating an infinite two-dimens...

In the crystal structure of the title mol-ecule, C(13)H(15)NO(5)S, the S and N atoms of the thia-zine ring exihibit the maximum deviations from the least-squares plane of 0.3008 (6) and 0.3280 (7) Å, respectively. The ring therefore adopts a half chair conformation. The thia-zine ring is twisted by an angle of 13.29 (7)° with respect to the aromatic ring. The isopropyl substituent is oriented a...

In the title compound, [Pb(C(10)H(11)O(2))(2)](n) or [Pb(hino)(2)](n), the lead(II) ion is chelated by two hinokitiolate ligands in a distorted square-pyramidal configuration, with Pb-O bond lengths in the range 2.327 (6)-2.479 (9) Å. The 6s(2) lone electron pair of the lead(II) ion becomes stereochemically active and is directed towards the apex of this pyramid. The crystal structure of the ti...

The relative configuration of the title compound, C(19)H(28)O(3)Si, which was synthesized using a dienolate-[2,3]-Wittig rearrangement, was corroborated by single-crystal X-ray diffraction analysis. The Si-C bond distances are in the range 1.858 (2)-1.880 (2) Å and an intra-molecular O-H⋯O hydrogen bond helps to stabilize the mol-ecular conformation.
