Low-temperature redetermination of trans-cyclohexane-1,2-dicarboxylic acid
نویسندگان
چکیده
The mol-ecule of the title compound, C(8)H(12)O(4), lies on a twofold rotation axis that passes through the mid-points of two opposite C-C bonds of the ring. Carboxyl groups of adjacent mol-ecules are linked by pairs of hydrogen bonds around a centre of inversion; this inter-action gives rise to a chain that runs along [101].

Redetermination of trans-cyclohexane-1,4-diammonium dichloride
A redetermination of the crystal structure of the title compound, C(6)H(16)N(2) (2+)·2Cl(-), was undertaken. All atomic coordinates including those of the H atoms were refined freely. The cation is located on a centre of symmetry. Important for the crystal structure are wavy hydrogen-bonded layers that are formed by ammonium groups and chloride anions, giving hydrogen-bonded rings.

The title complex, [Sn(CH(3))(2)(C(8)H(10)O(4))](n), was synthesized from cis-cyclo-hexane-1,2-dicarboxylic acid and dimethyl-tin dichloride. The complex has a bridging bis-bidentate carboxyl-ate group resulting in a zig-zag chain structure parallel to [001]. The Sn atom is six-coordinated and displays a distorted octa-hedral geometry.

Different optically active amido esters, mixed acid esters, amido acids, and diamides derived from trans-cyclopropane-1,2-dicarboxylic acid were prepared from the commercially available diethyl (±)-trans-cyclopropane-1,2-dicarboxylate. The key step was the Rhodococcus rhodochrous IFO 15564 catalyzed hydrolysis of the corresponding racemic amide. The amidase present in this microorganism showed ...
متن کاملA zirconium methacrylate oxocluster as precursor for the low-temperature synthesis of porous zirconium(IV) dicarboxylates.
The exchange of the monocarboxylate ligand of the zirconium methacrylate oxocluster Zr(6)O(4)(OH)(4)(OMc)(12) (OMc = CH(2)=CH(CH(3))COO) with dicarboxylic acids (trans,trans muconic acid and terephthalic acid) leads to porous zirconium dicarboxylates exhibiting the UiO-66 architecture; the mild reaction conditions allow the control of their particle size.
