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

ABSTRACT: 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.

Project description:In the polymeric complex of the title compound, {[AgNi(C(5)H(3)N(2)O(2))(2)(H(2)O)(2)]NO(3)·2H(2)O}(n), the Ag(I) ion displays an angular coordination geometry with two N atoms from pyrazine-2-carboxyl-ate ligands, and the Ni(II) ion is hexa-coordinated by two O atoms from two water mol-ecules, two O and two N atoms from pyrazine-2-carboxyl-ate ligands in a distorted octa-hedral geometry. In the crystal, the Ag(I) and Ni(II) ions lie on a mirror plane and an inversion centre, respectively. The complex chains, the nitrate ions and the uncoordinated water mol-ecules are linked together through O-H?O hydrogen bonds and weak Ag?O inter-actions [2.619?(17)-2.749?(17)?Å] into a three-dimensional network.

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.

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

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).

Poly[(?4-3-carb-oxy-pyrazine-2-carboxyl-ato)(?4-nitrato)dilithium].

Project description:In the title compound, [Li2(C6H3N2O4)2(NO3)] n , the two symmetry-independent Li(I) ions are each in a trigonal-bipyramidal coordination and are bridged by N,O-bonding ligands, forming mol-ecular ribbons propagating in [010]. Each Li(I) ion is also coordinated by two O atoms from nitrate ions, connecting the ribbons into a three-dimensional network. Very strong intra-molecular O-H?O hydrogen bonds occur between the carboxyl and the carboxylate group.

catena-Poly[[diaqua-rubidium(I)](?(2)-3-carboxy-pyrazine-2-carboxyl-ato)(?(2)-pyrazine-2,3-dicarboxylic acid)].

Project description:The structural unit of the title compound, [Rb(C(6)H(3)N(2)O(4))(C(6)H(4)N(2)O(4))(H(2)O)(2)](n), consists of one rubidium cation, one hydrogen pyrazine-2,3-dicarboxyl-ate anion, one pyrazine-2,3-dicarboxylic acid mol-ecule and two water mol-ecules. This formulation is repeated twice in the asymmetric unit as the rubidium cation lies on an inversion centre. Each anion or acid mol-ecule is linked to two rubidium cations, while the rubidium cation has close contacts to four symmetry-equivalent organic ligands, with two different coordination modes towards this cation. In addition, each rubidium cation is coordinated by two water O atoms, raising the coordination number to eight. One of the carboxyl groups of the acid holds its H atom, which forms a hydrogen bond to a coordinated water mol-ecule. The other carboxyl group is deprotonated in half of the ligands and protonated in the other half, taking part in a strong O-H?O hydrogen bond disordered over an inversion centre. The stabil-ization of the crystal structure is further assisted by O-H?O and O-H?N hydrogen-bonding inter-actions involving the water mol-ecules and carboxyl-ate O atoms.

Project description:The asymmetric unit of the polymeric title compound, {[Pr(2)(C(5)H(4)N(3)O(2))(5)(CHO(2))(H(2)O)(5)]·6H(2)O}(n), has two independent Pr(III) atoms; one is coordinated by two water mol-ecules and the other by three water mol-ecules. The first is N,O-chelated by three 3-amino-pyrazine-2-carboxyl-ate ions, whereas the second is chelated by two carboxyl-ate ions; both exist in a monocapped square-anti-prismatic geometry. The polymeric chains that run along the a axis inter-act with the lattice water mol-ecules, generating a three-dimensional hydrogen-bonded network. The formate ion is disordered over two positions with respect to the non-coordinated atoms in a 1:1 ratio.

Project description:The title compound, [Sr(C(10)H(6)NO(2))(2)(H(2)O)(2)](n), contains an eight-coordinate Sr(II) ion displaying a distorted square-anti-prismatic geometry, two quinoline-3-carboxyl-ate ligands and two terminal water mol-ecules. The Sr(II) atom is surrounded by six carboxyl-ate O atoms from four separate quinoline-3-carboxyl-ate ligands and two O atoms from two coordinated water mol-ecules. The bridging carboxyl-ate O atoms [Sr-O = 2.498?(3) and 2.495?(3)?Å] link Sr(II) atoms, forming a chain substructure extending along the c axis.

Project description:In the crystal structure of the title compound, [Zn(C(7)H(7)N(2)O(4))(2)(H(2)O)(2)]·3H(2)O, the Zn(II) ion, located an inversion center, is N,O-chelated by two 5-carb-oxy-2-ethyl-1H-imidazole-4-carboxyl-ate anions and further coordinated by two water mol-ecules in a distorted octa-hedral geometry. The carb-oxy group links with the carboxyl-ate group of the same ligand via an intra-molecular O-H?O hydrogen bond. An extensive inter-molecular N-H?O and O-H?O hydrogen-bonded network exists in the crystal structure. One disordered lattice water mol-ecule is half-occupied and is located close to an inversion center.
