Catena-Poly[[diaqua-lithium]-?-[rac-cis-(2-carb-oxy-cyclo-hexane-1-carboxyl-ato-?O:O]].

ABSTRACT: 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).

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 μ(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.

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 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.

catena-Poly[[(6-carb-oxy-pyrazine-2-carboxyl-ato)lithium]-?-aqua].

Project description:The asymmetric unit of the title compound, [Li(C(6)H(3)N(2)O(4))(H(2)O)](n), contains an Li(I) ion with a distorted trigonal-bipyramidal coordination environment. It is chelated by a singly protonated ligand mol-ecule via its heterocyclic N atom, by two O aoms, each donated by an adjacent carboxyl-ate group, and is further coordinated by a water O atom which acts as a bridge, forming a mol-ecular ribbon. A proton attached to one of the carboxyl-ate O atoms is situated on an inversion centre and forms a short centrosymmetric hydrogen bond, generating mol-ecular layers parallel to the ac plane. These layers are held together by weak O-H?O hydrogen bonds in which the coordinated water mol-ecules act as donors, whereas carboxyl-ate O atoms are acceptors.

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).

catena-Poly[[(diaqua-zinc)-?-3-carb-oxy-pyrazine-2-carboxyl-ato-?N,O;N,O] nitrate].

Project description:The crystal structure of the title compound, {[Zn(C(6)H(3)N(2)O(4))(H(2)O)(2)]NO(3)}(n), is built of zigzag cationic chains propagating in [010] with nitrate anions located in the space between the chains. The Zn(II) ion is coordinated by N and O atoms of two symmetry-related ligands in equatorial sites, and by two water O atoms at the axial sites of a distorted octa-hedron. One carboxyl-ate group of the ligand remains protonated, serving as a donor in a short intra-molecular O-H?O hydrogen bond. The coordinated water mol-ecules are donors and the nitrate O atoms act as acceptors in a network of O-H?O hydrogen bonds.

The chains are linked by O-H?N and O-H?O hydrogen bonds, giving a three-dimensional framework structure.
