(1R,2S,4S,5R)-Cyclo-hexane-1,2:4,5-tetra-carb-oxy-lic dianhydride.

ABSTRACT: The title compound, C(10)H(8)O(6), a promising raw material to obtain colorless polyimides which are applied to microelectronic and optoelectronic devices, adopts a folded conformation in which the dihedral angle between the two anhydro rings is 55.15?(8)°. The central six-membered ring assumes a conformation inter-mediate between boat and twist-boat. In the crystal, mol-ecules are linked by weak C-H?O inter-actions, forming a layer parallel to the bc plane.

(1S*,2S*,4R*,5R*)-Cyclo-hexane-1,2,4,5-tetra-carb-oxy-lic acid.

Project description:The title compound, C10H12O8, a prospective raw material for colourless polyimides which are applied to electronic and microelectronic devices, lies about an inversion centre and the cyclo-hexane ring adopts a chair conformation. Two crystallographycally independent carb-oxy-lic acid groups on adjacent C atoms are in equatorial positions, resulting in a mutually trans conformation. In the crystal, O-H?O hydrogen bonds around an inversion centre and a threefold rotoinversion axis, respectively, form an inversion dimer with an R 2 (2)(8) motif and a trimer with an R 3 (3)(12) motif.

4,4'-Bipyridine-cyclo-hexane-1,2,4,5-tetra-carb-oxy-lic acid (1/1).

Project description:In the title 1:1 adduct, C(10)H(8)N(2)·C(10)H(12)O(8), the dihedral angle between the pyridine rings in the 4,4-bipyridine molecule is 8.33 (13)°. In the crystal, the cyclo-hexane-1,2,4,5-tetra-carb-oxy-lic acid mol-ecules inter-act with each other through inter-molecular O-H⋯O hydrogen bonds, forming an infinite chain along the a axis, which is further linked perpendicularly by O-H⋯N hydrogen bonds involving bipyridine, resulting in a supra-molecular corrugated sheet parallel to the (110) plane.

Project description:In the title compound, C(15)H(21)NO(5)S, two crystallographically independent mol-ecules are linked into a dimer by a pair of N-H⋯O hydrogen bonds, forming an R(2) (2)(8) ring motif. In the crystal, mol-ecules are further linked by inter-molecular O-H⋯O hydrogen bonds into a two-dimensional network parallel to (012). Additional stabilization is provided by weak inter-molecular C-H⋯O hydrogen bonds.

Project description:The title compound, C38H50N2O7, represents a chiral β-proline dipeptide. Corresponding stereogenic centres of constituting pyrrolidine units have opposite absolute configurations. The central amide fragment is planar within 0.1 Å and adopts a Z configuration along the N-CO bond. In the crystal, the hydrogen atoms of the methyl-ene groups form several short inter-molecular C-H⋯O contacts with the carbonyl oxygen atoms of an adjacent mol-ecule. The only active amino hydrogen atom is not involved in hydrogen bonding.

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.

Crystal structure of 4-{[(2,4-di-hydroxy-benzyl-idene)amino]-meth-yl}cyclo-hexane-carb-oxy-lic acid.

Project description:In the title compound, C15H19NO4, the cyclo-hexyl ring adopts a chair conformation with both exocyclic C-C bonds in equatorial orientations. The dihedral angle between the basal plane of cyclo-hexyl ring and the 2,4-di-hydroxy-benzaldehyde moiety is 84.13 (13)°. An intra-molecular O-H⋯N hydrogen bonds closes an S(6) ring. In the crystal, Oc-H⋯Op (c = carb-oxy-lic acid, p = phenol) hydrogen bonds link the mol-ecules into [100] C(13) chains whereas an Op-H⋯Oc hydrogen bond generates [101] C(15) chains. Together, these bonds generate (010) sheets incorporating R 2 (2)(20) loops. Weak C-H⋯O and C-H⋯π inter-actions also occur.

(1R*,2S*)-N,N'-Bis[(E)-1H-pyrrol-2-yl-methyl-idene]cyclo-hexane-1,2-diamine monohydrate.

Project description:The title compound, C16H20N4·H2O, was synthesized from cis-1,2-diamino-cyclo-hexane (a racemic mixture of the (1R,2S) and (1S,2R) enanti-omers). The compound crystallized with two mol-ecules (A and B) in the asymmetric unit with a single water solvent mol-ecule per Schiff base mol-ecule. Mol-ecules A and B have similar conformations as illustrated by the least-squares-fit with an r.m.s. deviation of 0.242 Å. The mol-ecules within the asymmetric unit are bridged by hydrogen bonds to the two water mol-ecules, resulting in a heterotetramer. The water mol-ecule acts as both a hydrogen-bond donor and acceptor. The pyrrole-imine units are not co-planar, making an angle of 73.9 (3)° and 76.9 (3)° in mol-ecules A and B, respectively.
