چکیده
In the title coordination polymer, [Pb(C(7)H(3)NO(4))](n), the Pb(II) ion is eight-coordinated in a distorted square-anti-prismatic geometry formed by one pyridine N atom and seven carboxyl-ate O atoms from four pyridine-2,3-dicarboxyl-ate (pda) anions. In the pda anion, the dihedral angles between the pyridine ring and carboxyl-ate groups are 19.5 (6) and 73.3 (6)°. The carboxyl-ate groups of the pda anions bridge the Pb ions, forming a two-dimensional coordination polymer parallel to (100). Weak inter-molecular C-H⋯O hydrogen boning is present in the crystal structure.

In the title polymeric complex, [Sr(C(7)H(3)NO(4))(H(2)O)(2)](n), the Sr(II) atom is eight-coordinated by four O atoms and one N atom of four pyridine-2,4-dicarboxyl-ate (py-2,4-dc) ligands and three O atoms of three coordinated water mol-ecules in a dodeca-hedral geometry. These units are connected via the carboxyl-ate O atoms and water mol-ecules, building polymeric layers parallel to (100). ...

In the title coordination polymer, {[Mn(C(7)H(3)NO(4))(H(2)O)(2)]·2H(2)O}(n), the Mn(II) ion is coordinated in a distorted octahedral environment by the O atoms of two water mol-ecules, one N and one O atoms of the chelating pyridine-2,3-dicarboxyl-ate (PDC) dianion, and two axial bridging carboxyl-ate O atoms from two adjacent PDC ligands. The fully deprotonated PDC anion acts a μ(3)-bridging ...

In the title compound, {[Cu(C(7)H(3)NO(4))(H(2)O)(3)]·H(2)O}(n), the Cu(II) ion is bonded to three water mol-ecules, one N,O-bidentate pyridine-2,3-dicarboxyl-ate dianion and one O-bonded symmetry-generated dianion, resulting in a distorted CuNO(5) octa-hedral geometry. The bridging ligand results in an infinite chain. A network of O-H⋯O hydrogen bonds helps to establish the crystal structure.
