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

ABSTRACT: 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.

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-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.

Poly[di-?(2)-aqua-?(2)-(5-methyl-pyrazine-2-carboxyl-ato)-(5-methyl-pyrazine-2-carboxyl-ato)-?(3)-nitrato-trilithium].

Project description:The asymmetric unit of the title compound, [Li(3)(C(6)H(5)N(2)O(2))(2)(NO(3))(H(2)O)(2)](n) contains three Li(I) ions, two ligand anions, two water mol-ecules and a nitrate anion. Related by a centre of inversion, they form a centrosymmetric mol-ecular cluster in which one of the Li(I) ions shows trigonal-bipyramidal and the other two distorted tetra-hedral coordination. Li(I) ions are bridged by water O atoms and carboxyl-ate O atoms donated by one of the ligands. The clusters, bridged by two nitrato O atoms, form mol-ecular columns along [010], which are held together by O-H?O and O-H?N hydrogen bonds and ?-? inter-actions [centroid-centroid distances = 3.694?(1) and 3.796?(1)?Å].

Poly[triaquabis-(?(2)-3-carboxy-pyrazine-2-carboxyl-ato)dilithium(I)].

Project description:In the title compound, [Li(2)(C(6)H(3)N(2)O(4))(2)(H(2)O)(3)](n), the coordination number for both independent Li(+) cations is five. One of the Li(+) ions has a distorted trigonal-bipyramidal geometry, coordinated by one of the carboxyl O atoms of a 3-carboxy-pyrazine-2-carboxyl-ate ligand, two O atoms from two water mol-ecules, and an N and a carboxyl-ate O atom of a second 3-carboxy-pyrazine-2-carboxyl-ate ligand. The other Li(+) ion also has a distorted trigonal-bipyramidal geometry, coordinated by one water mol-ecule and two 3-carboxy-pyrazine-2-carboxyl-ate ligands through an N and a carboxyl-ate O atom from each. One of the carboxyl groups of the two ligands takes part in an intra-molecular O-H?O hydrogen bond. The stabilization of the crystal structure is further assisted by O-H?O, O-H?N and C-H?O hydrogen-bonding inter-actions involving the water mol-ecules and carboxyl-ate O atoms.

Poly[di-?-aqua-?(4)-(pyrazine-2,5-dicarboxyl-ato)-dilithium(I)].

Project description:In the title coordination polymer, [Li(2)(C(6)H(2)N(2)O(2))(H(2)O)(2)](n) the pyrazine-2,5-dicarboxyl-ate dianionic ligand bridges two symmetry-independent Li(+) ions using both its N,O-chelating sites. The carboxyl-ate O atom of one of them also bridges to another Li(+) ion, while the second O atom of this group is bonded to another Li(+) ion. Two symmetry-independent water O atoms participate also in the bridging system, which gives rise to a polymeric three-dimensional framework. Both Li(+) ions show distorted trigonal-bipyramidal LiNO(4) coordination geometries, with the N atom in an axial site in both cases. The packing is consolidated by O-H?O hydrogen bonds, which occur between water mol-ecules as donors and carboxyl-ate O atoms as acceptors.

catena-Poly[[bis-(?-3-amino-pyrazine-2-carboxyl-ato)-?N,O:O;?O:N,O)dilithium]-di-?-aqua].

Project description:The title compound, [Li(C(5)H(4)N(3)O(2))(H(2)O)](n), is composed of centrosymmetric dinuclear units, in which the Li(I) ions are bridged by two carboxyl-ate O atoms donated by two ligands. The dinuclear unit is nearly planar [r.m.s. deviation = 0.0125?(2)?Å]. The Li(I) ion is coordinated by an N,O-chelating ligand, a bridging carboxyl-ate O atom from another ligand and two bridging water O atoms in a distorted trigonal-bipyra-midal geometry. The water O atoms bridge the dinuclear units into a polymeric mol-ecular column along [010]. The columns are held together by O-H?O and N-H?N hydrogen bonds. An intra-molecular N-H?O inter-action also occurs.

Acridinium 3-carb-oxy-pyrazine-2-carboxyl-ate.

Project description:The title ion pair, C(13)H(10)N(+)·C(6)H(3)N(2)O(4) (-), contains a protonated acridine cation and a 3-carb-oxy-pyrazine-2-carboxyl-ate monoanion, which are linked together through O-H⋯O, N-H⋯O and weak C-H⋯O hydrogen bonds. These hydrogen bonds generate a C(10) chain graph-set motif. The crystal structure is further stabilized by extensive π-π stacking inter-actions between nearly parallel [dihedral angle = 1.21(2)°] acridine systems. The shortest distance between the centroids of the six-membered rings within the cations is 3.6315 (8) Å. In addition, C-H⋯π edge-to-face inter-actions are present.

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.

Poly[aqua-(?-pyrazine-2-carboxyl-ato-?N,O:O)(?-pyrazine-2-carboxyl-ato-?N,O:O')lead(II)].

Project description:The polymeric structure of the title compound, [Pb(C(5)H(3)N(2)O(2))(2)(H(2)O)](n), is built up from centrosymmetric [Pb(C(5)H(3)N(2)O(2))(2)(H(2)O)](2) dimers, which are bridged by ligand carboxyl-ate O atoms. The Pb(II) ion adopts an irregular PbN(2)O(5) coordination polyhedron; it is chelated by one N,O-bidentate ligand and also bonds to a water O atom. A second N,O-bidentate ligand forms the dimer bridge and another bridging O atom from a nearby dimer also bonds to the Pb(II) ion, leading to layers propagating in (100). A network of O-H?O hydrogen bonds operates between water O atoms (donors) and carboxyl-ate O atoms (acceptors).

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.
