ABSTRACT
In the title compound, [Ag(2)(C(10)H(6)NO(2))(2)](n), the Ag(I) atom is coordinated by one N atom and two O atoms from three quinoline-3-carboxyl-ate ligands in a T-shaped fashion, with an additional Agâ¯Ag distance of 2.9468â (6)â Å. The ligands connect the Ag(I) atoms into a double-chain structure along [010]. Weak Agâ¯O inter-actions [Agâ¯O = 2.802â (3) and 2.877â (4)â Å] link the double-chains into a layer network parallel to (101). π-π inter-actions are also observed in the layer network [centroid-centroid distances = 3.780â (3) and 3.777â (3)â Å].
ABSTRACT
In the title compound, [Cd(C(10)H(6)NO(2))(2)](n), the Cd(II) atom is coordinated by three O atoms and two N atoms from four quinoline-3-carboxyl-ate (L(-)) ligands, leading to a distorted trigonal-bipyramidal geometry. The L(-) ligands link the Cd(II) atoms into a plane parallel to (100), with one ligand being tridentate, coordinating via the N atom and chelating a second Cd atom, and the other being bidentate, bridging two Cd atoms via the N and one O atom.. This two-dimensional network extends into a double-layer network by π-π inter-actions, with centroid-centroid distances of 3.680â (2) and 3.752â (2)â Å. Another type of π-π inter-action between pyridine rings [centroid-centroid distance = 3.527â (2)â Å] leads to a three-dimensional supra-molecular architecture.
