چکیده
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.

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 gr...

In the title silver(I) coordination polymer, {[Ag(2)(C(6)H(5)N(2)O(2))(2)(H(2)O)(2)]·2H(2)O}(n), the [Ag(2)(μ(2)-H(2)O)(H(2)O)] cores are extended by anti-parallel 5-methyl-pyrazine-2-carboxyl-ate (L) ligands, forming a novel double-chain structure. Both Ag(+) cations show a distorted square-pyramidal coordination. Ag1 is bonded to two water molecules, one L N atom, one N atom and one carboxyla...
