Poly[diaqua-(μ(2)-oxalato-κO,O:O,O)(μ(2)-pyrazine-2-carboxyl-ato-κN,O:O,O')neodymium(III)].

ABSTRACT: In the title complex, [Nd(C(5)H(3)N(2)O(2))(C(2)O(4))(H(2)O)(2)](n), the Nd(III) atom is ten-coordinated by one N atom and three O atoms from two pyrazine-2-carboxyl-ate ligands, four O atoms from two oxalate ligands and two water mol-ecules in a distorted bicapped square-anti-prismatic geometry. The two crystallographically independent oxalate ligands, each lying on an inversion center, act as bridging ligands, linking Nd atoms into an extended zigzag chain. Neighboring chains are linked by the pyrazine-2-carboxyl-ate ligands into a two-dimensional layerlike network in the (10) plane. The layers are further connected by O-H⋯O and O-H⋯N hydrogen bonds, forming a three-dimensional supra-molecular network.

Poly[aqua-(μ-pyrazine-2-carboxyl-ato-κN,O:O)(μ-pyrazine-2-carboxyl-ato-κN,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).

catena-Poly[[(diaqua-zinc)-μ-3-carb-oxy-pyrazine-2-carboxyl-ato-κN,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.
