Rac-2-Amino-pyridinium cis-2-carb-oxy-cyclo-hexane-1-carboxyl-ate.

ABSTRACT: In the structure of the title compound, C(5)H(7)N(2) (+)·C(8)H(11)O(4) (-), the cis anions associate through head-to-tail carb-oxy-lic acid-carboxyl O-H?O hydrogen bonds [graph set C(7)], forming chains which extend along c and are inter-linked through the carboxyl groups, forming cyclic R(2) (2)(8) associations with the pyridinium and an amine H-atom donor of the cation. Further amine-carboxyl N-H?O inter-actions form enlarged centrosymmetric rings [graph set R(4) (4)(18)] and extensions down b, giving a three-dimensional structure.

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.

Project description:In the structure of the title molecular salt, C(5)H(7)N(2) (+)·C(8)H(11)O(4) (-), the cis monoanions associate through short O-H?O hydrogen bonds in the carb-oxy-lic acid groups [graph set C(7)], forming zigzag chains which extend along the c axis.

Project description:In the structure of the title compound, [Li(C(8)H(11)O(4))(H(2)O)(2)](n), the distorted tetra-hadral LiO(4) coordination sphere comprises two water mol-ecules and two carboxyl O-atom donors from separate bridging cis-2-carb-oxy-cyclo-hexane-1-carboxyl-ate monoanions [Li-O = 1.887?(4)-1.946?(3)?Å], giving chain substructures which extend along [010]. Water-water and water-carboxyl O-H?O hydrogen bonds stabilize these chain structures and provide inter-chain links, resulting in a two-dimensional layered structure extending parallel to (100).

rac-4-Carbamoylpiperidinium cis-2-car-boxy-cyclo-hexane-1-carboxyl-ate.

Project description:In the title racemic salt, C(6)H(13)N(2)O(+)·C(8)H(11)O(4) (-), formed from the reaction of cis-cyclo-hexane-1,2-dicarb-oxy-lic anhydride with isonipecotamide, the cations are linked into duplex chain substructures through both centrosymmetric cyclic head-to-head 'amide motif' hydrogen-bonding associations [graph set R(2) (2)(8)] and 'side-by-side' R(2) (2)(14) associations. The anions are incorporated into the chains through cyclic R(4) (3)(10) inter-actions involving amide and piperidinium N-H⋯O(carbox-yl) hydrogen bonds which, together with inter-anion carb-oxy-lic acid O-H⋯O(carbox-yl) hydrogen bonds, give a two-dimensional layered structure extending along (011).

2-Amino-4-methyl-pyridinium 6-carb-oxy-pyridine-2-carboxyl-ate sesquihydrate.

Project description:In the title compound, C(6)H(9)N(2) (+)·C(7)H(4)NO(4) (-)·1.5H(2)O, extensive O-H?O, O-H?N, N-H?O and C-H?O hydrogen bonds, as well as ion pairing, ?-? stacking inter-actions [centroid-centroid distances = 3.4690?(8) and 3.6932?(8)?Å between aromatic rings] occur in the crystal. There are hydrogen-bonding inter-actions between water mol-ecules, which result in cyclic tetra-meric water clusters. One of the water O molecules has half occupancy. In the anion molecules, the -CO(2) and -CO(2)H groups make torsion angles of 1.73?(18) and -12.14?(18)° with respect to the ring.

Project description:The structure of the title salt, (C5H7N2)[Fe(C6H4O2)(C6H5O2)], consists of 3-amino-pyridinium cations and 1'-carb-oxy-ferrocene-1-carboxyl-ate monoanions.

Project description:In the title salt, C(6)H(9)N(2) (+)·C(5)H(7)O(4) (-), the 2-amino-5-methyl-pyridinium cation is essentially planar, with a maximum deviation of 0.008?(1)?Å.
