چکیده
In the title complex, [Fe(C(2)O(4))(C(5)H(4)N(2)O(4))](n), the Fe(II) ion is coordinated by two oxalate anions and a pyrimidine-2-carb-oxy-lic acid ligand in a slightly distorted octa-hedral geometry. Each oxalate anion chelates to two Fe(II) ions, forming chains along the a axis. The chains are further connected by O-H⋯O and C-H⋯O hydrogen bonds, stabilizing the structure. An intra-molecular O-H⋯N inter-action results in a five-membered ring.

In the title compound, [HgCl(2)(C(6)H(5)NO(2))(2)](n), the Hg(II) cation is located on an inversion center and is six-coordinated in a distorted octa-hedral geometry by two N atoms from two pyridine-3-carb-oxy-lic acid mol-ecules and four bridging Cl(-) anions. The bridging function of the Cl(-) anions leads to polymeric chains running along the a axis. One Hg-Cl bond is much longer than the ot...

The title compound, [Ni(C(2)O(4))(C(5)H(5)N)(2)](n), was synthesized under hydro-(solvo)thermal conditions. The Ni(II) atom, lying on a twofold rotation axis, has an octa-hedral coordination geometry involving two N atoms from two pyridine ligands and four O atoms from two oxalate ligands. The Ni atoms are connected by the tetra-dentate bridging oxalate ligands into a one-dimensional zigzag chain.
متن کاملCrystal structure of catena-poly[diammonium [di-μ-oxalato-cuprate(II)]]
The structure of the title compound, {(NH4)2[Cu(C2O4)2]} n , at 100 K has monoclinic (P21/c) symmetry with the CuII atom on an inversion center. The compound has a polymeric structure due to long Cu⋯O inter-actions which create [Cu(C2O4)2] chains along the a axis. The structure also displays inter-molecular N-H⋯O hydrogen bonding, which links these chains into a three-dimensional network.
