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

ABSTRACT: 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.

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.

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.

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.

Project description:The polymeric title compound, [Ca(C(6)H(2)N(2)O(4))(H(2)O)](n), was synthesized from pyrazine-2,3-dicarb-oxy-lic acid and calcium dichloride under hydro-thermal conditions. The Ca(2+) cation is seven-coordinated by five O atoms and one N atom of four pyrazine-2,3-dicarboxyl-ate anions, and one water mol-ecule. The complete deprotonated pyrazine-2,3-dicarboxyl-ate anion adopts a μ(4)-coordination mode, resulting in the formation of a three-dimensional structure.

Poly[[hepta-μ(2)-aqua-bis-(μ(2)-pyrazine-2-carboxyl-ato)dibarium] bis-(pyrazine-2-carboxyl-ate)].

Project description:In the layered title coordination polymer, {[Ba(2)(C(5)H(3)N(2)O(2))(2)(H(2)O)(7)](C(5)H(3)N(2)O(2))(2)}(n), the coordination geometries around the two independent Ba(II) ions can be described as bicapped square-anti-prismatic [BaNO(9)] arrangements. A two-dimensional polymeric framework with (6,3) topology can be observed in the ac plane, the nodes being provided by Ba(II) ions and the connectors being N and O atoms belonging to pyrazine-2-carboxyl-ate ligands and O atoms of bridging water mol-ecules. Non-coordinating pyrazine-2-carboxyl-ate ions are located between the polymeric layers in the crystal and are interconnected through extensive O-H⋯N,O hydrogen bonding.

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].

catena-Poly[bis-(4-amino-pyridinium) [[tetra-aqua-nickel(II)]-?-benzene-1,2,4,5-tetra-carboxyl-ato] dihydrate].

Project description:The asymmetric unit of the title compound, {(C(5)H(7)N(2))(2)[Ni(C(10)H(2)O(8))(H(2)O)(4)]·2H(2)O}(n), contains an Ni(II) atom, two water mol-ecules of coordination, one half of a benzene-1,2,4,5-tetra-carboxyl-ate (btec) anionic ligand, one 4-amino-pyridinium cation (papy) and an uncoordinated water mol-ecule. The metal center lies on an inversion center and adopts an octa-hedral geometry with the carboxyl-ate groups tilted out of the mean plane formed by the btec. In the crystal, mol-ecules are linked into one-dimensional coordination polymers running along the ac diagonal. The crystal structure is consolidated by N-H?O and O-H?O hydrogen bonds.

catena-Poly[[di-aqua-bis-(4-formyl-benzo-ato-κO (1))nickel(II)]-μ-pyrazine-κ(2) N:N'].

Project description:In the title polymeric compound, [Ni(C8H5O3)2(C4H4N2)(H2O)2] n , the Ni(II) atom is located on a twofold rotation axis and has a slightly distorted octa-hedral coordination sphere. In the equatorial plane, it is coordinated by two carboxyl-ate O atoms of two symmetry-related monodentate formyl-benzoate anions and by two N atoms of the bridging pyrazine ligand, which is bis-ected by the twofold rotation axis. The axial positions are occupied by two O atoms of the coordinating water mol-ecules. In the formyl-benzoate anion, the carboxyl-ate group is twisted away from the attached benzene ring by 7.0 (6)°, while the benzene and pyrazine rings are oriented at a dihedral angle of 66.2 (3)°. The pyrazine ligands bridge the Ni(II) cations, forming polymeric chains running along the b-axis direction. Intra-molecular O-H⋯O hydrogen bonds link the water ligands to the carboxyl-ate O atoms. In the crystal, water-water O-H⋯O hydrogen bonds link adjacent chains into layers parallel to the bc plane. Pyrazine-formyl C-H⋯O hydrogen bonds link the layers, forming a three-dimensional network. There are also weak C-H⋯π inter-actions present. The title compound is isotypic with the copper(II) complex [Çelik et al. (2014a). Acta Cryst. E70, m4-m5].

catena-Poly[[aqua-(1,10-phenanthroline)cadmium(II)]-μ-benzene-1,4-di-carboxyl-ato].

Project description:The title compound, [Cd(C(8)H(4)O(4))(C(12)H(8)N(2))(H(2)O)](n), is a new coordination polymer of benzene-1,4-dicarboxyl-ate with cadmium(II) and 1,10-phenanthroline. The Cd(II) ion is coordinated by two N atoms from the 1,10-phenanthroline mol-ecule, three O atoms from two crystallographically independent benzene-1,4-dicarboxyl-ate ligands and the O atom of a coordinated water mol-ecule, forming a heavily distorted octa-hedron. The 1,10-phenanthroline ligand is approximately planar within 0.073 (4) Å. The two different benzene-1,4-dicarboxyl-ate ligands each coordinate to two Cd(II) ions in bidentate and monodentate modes, forming an infinite zigzag chain. Adjacent chains are packed tightly by strong π-π inter-actions [centroid-centroid distances = 3.851 (2) and 3.859 (2) Å] between the aromatic rings of the benzene-1,4-dicarboxyl-ate ligand and the 1,10-phenanthroline of a neighboring chain, forming a sheet parallel to (011). Different sheets are linked together via O-H⋯O hydrogen bonds between the coordinated water mol-ecules and the O atoms of the carboxyl-ate groups, forming a three-dimensional network.
