RESUMO
In the title compound, [Cd(C4H5NO4)(H2O)2] n , the Cd(II) atom exhibits a distorted octa-hedral coordination geometry, defined by one N atom and three O atoms from two iminodi-acetate (IDA) ligands and two water molecules. The tridentate IDA ligand additionally bridges via one of its carboxylate O atoms to another Cd(II) atom, thus forming a zigzag chain along [001]. A three-dimensional network is completed by inter-molecular O-Hâ¯O and N-Hâ¯O hydrogen bonds.
RESUMO
The title compound, {[ZnCl(C13H12F2N6O)2]Cl·2H2O} n , is a two-dimensional coordination polymer. The Zn(II) atom is six-coordinated by four N atoms from four 2-(2,4-di-fluoro-phen-yl)-1,3-bis-(1,2,4-triazol-1-yl)propan-2-ol (HFlu) ligands and by two Cl atoms in a distorted octa-hedral geometry. Two Cl atoms bridge two Zn(II) atoms, forming a centrosymmetric dinuclear unit. The HFlu ligands connect the dinuclear units into a 4(4) net parallel to (001) when the dinuclear unit is considered as a node. O-Hâ¯O and O-Hâ¯Cl hydrogen bonds link the cationic layer, free chloride anions and lattice water mol-ecules. Intra-layer π-π inter-actions between the triazole rings are observed [centroid-centroid distance = 3.716â (6)â Å].
RESUMO
The title compound, [Pb(2)(C(2)O(4))(NO(3))(2)(C(10)H(8)N(2))(2)(H(2)O)(2)], was synthesized hydro-thermally. The binuclear complex mol-ecule is centrosymmetric, the inversion centre being located at the mid-point of the oxalate C-C bond. The Pb(II) ion is hepta-coordinated by the O atom of one water mol-ecule, two oxalate O atoms, two nitrate O atoms and two 2,2'-bipyridine N atoms, forming an irregular coordination environemnt. Inter-molecular O-Hâ¯O hydrogen bonds between water mol-ecules and oxalate and nitrate ions result in the formation of layers parallel to (010). π-π inter-actions between pyridine rings in adjacent layers, with centroid-centroid distances of 3.584â (2)â Å, stabilize the structural set-up.
