Cis-Cyclo-hexane-1,4-dicarboxylic acid.

ABSTRACT: In the title compound, C(8)H(12)O(4), the two carboxyl groups are on the same side of the cyclohexane ring and the ring adopts a chair conformation. Adjacent mol-ecules related by an inversion centre are linked by pairs of O-H?O hydrogen bonds, forming a zigzag chain along [1].

Low-temperature redetermination of trans-cyclo-hexane-1,2-dicarboxylic acid.

Project description: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].

Poly[di-?-cis-cyclo-hexane-1,4-dicarboxyl-ato-?-trans-cyclo-hexane-1,4-dicarboxyl-ato-bis-[dipyrido[3,2-a:2',3'-c]phenazine]trimanganese(II)].

Project description:In the title compound, [Mn(3)(C(8)H(10)O(4))(3)(C(18)H(10)N(4))(2)], one Mn atom and one cyclohexane-1,4-dicarboxylate (chdc) ligand are located on centres of inversion. One of the two independent Mn atoms is seven-coordinate, binding to five carboxyl-ate O atoms from different chdc ligands and two phenanthrene N atoms from a dipyrido[3,2-a:2',3'-c]phenazine (L) ligand, while the second Mn atom is six-coordinate, binding to six carboxyl-ate O atoms from different chdc ligands. The cis-chdc ligands bridge the trinuclear Mn(II) clusters, forming chains, which are further linked into a three-dimensional network.

2,2'-[(E,E)-cis-(Cyclo-hexane-1,4-di-yl)bis-(nitrilo-methanylyl-idene)]diphenol.

Project description:In the title compound, C(20)H(22)N(2)O(2), the asymmetric unit contains two independent half-mol-ecules, which are both completed by crystallographic inversion symmetry. The cyclo-hexane rings of both mol-ecules adopt chair conformations; the N atoms are in equatorial orientations in one mol-ecule and in axial orientations in the other. Both mol-ecules feature two intra-molecular O-H?N hydrogen bonds, which generate S(6) rings.

Cyclo-hexane-1,4-dicarb-oxy-lic acid-pyridinium-4-olate (1/1).

Project description:In the title adduct, C5H5NO·C8H12O4, the heterocycle exists in its zwitterionic form. The cyclo-hexane ring exhibits a chair conformation with the carb-oxy-lic acid groups in equatorial and axial orientations. In the crystal, mol-ecules are linked through charge-assisted O-H?O(-), N(+)-H?O(-) and N(+)-H?O hydrogen bonds, and an additional series of C-H?O contacts, giving a pleated two-dimensional hydrogen-bonded network parallel to (-204).

rac-cis-Cyclo-hexane-1,2-dicarb-oxy-lic acid-isoquinoline (1/1).

Project description:In the crystal structure of the title mol-ecular adduct, C(9)H(7)N·C(8)H(12)O(4), the two species are -linked through a carb-oxy-lic acid-isoquinoline O-H?N hydrogen bond. These mol-ecular pairs then inter-associate through the second acid group of the cis-cyclo-hexane-1,2-dicarb-oxy-lic acid molecules, forming a classic centrosymmetric cyclic head-to-head carb-oxy-lic acid-carboxyl O-H?O hydrogen-bonding association [graph-set R(2) (2)(8)], giving a zero-dimensional (cluster) structure, consisting of two of each species.

Redetermination of trans-cyclo-hexane-1,4-diammonium dichloride.

Project description: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.

Project description:The title compound, C(16)H(18)N(2)S(2), lies about an inversion center with only half of the mol-ecule in the asymmetric unit. The cyclo-hexane ring adopts a chair conformation, and the terminal thio-phene rings are in a transoid orientation, with an S?S separation between the two terminal 2-thio-phene rings of 11.6733?(9)?Å.

catena-Poly[diaqua-(cis-cyclo-hexane-1,2-dicarboxyl-ato)cadmium].

Project description:In the title polymer, [Cd(C(8)H(10)O(4))(H(2)O)(2)](n), the Cd(II) cation is coordinated by five carboxyl-ate O atoms from three different cyclo-hexane-1,2-dicarboxyl-ate anions and two O atoms from two water mol-ecules, displaying a distorted CdO(7) pentagonal-bipyramidal geometry. Each anion acts as a ?(3)-bridge, linking symmetry-related Cd(II) ions into a layer parallel to (010). In the crystal, numerous O-H?O and C-H?O hydrogen bonds occur. The coordinated water mol-ecules and carboxyl-ate O atoms act as donors or acceptors in the formation of these hydrogen-bonding inter-actions.

e,e-trans-Cyclo-hexane-1,4-carb-oxy-lic acid-hexa-methyl-ene-tetra-mine (1/2).

Project description:The asymmetric unit of the title compound, 2C(6)H(12)N(4)·C(8)H(12)O(4), contains one half-mol-ecule of e,e-trans-cyclo-hexane-1,4-dicarb-oxy-lic acid (the complete molecule being generated by inversion symmetry) and one mol-ecule of hexa-methyl-ene-tetra-mine (HMTA), which are connected by O-H?N hydrogen bonds. This forms isolated trimers that pack in a herringbone fashion.

rac-Ammonium cis-2-carb-oxy-cyclo-hexane-1-carboxyl-ate.

Project description:In the structure of the title compound, NH(4) (+)·C(8)H(11)O(4) (-), the carboxyl and carboxyl-ate groups of the cation adopt C-C-C-O torsion angles of 174.9?(2) and -145.4?(2)°, respectively, with the alicyclic ring. The ammonium H atoms of the cations give a total of five hydrogen-bonding associations with carboxyl-ate O-atom acceptors of the anion which, together with a carboxyl O-H?O(carboxyl-ate) inter-action give sheet structures which lie in the (101) planes.
