Poly[bis[μ(2)-2-(2-pyridylmethylamino)ethanesulfonato]cadmium(II)]
The title compound [Cd(C(8)H(11)N(2)O(3)S)(2)](n), is a two-dimensional coordination polymer based on a Cd(2+) atom and deprotonated 2-(2-pyridylmethylamino)ethanesulfonic acid (Hpmt). The complex has molecular symmetry C (i) as a consequence of the Cd(II) being located on an inversion centre. Two...

Sumario: | The title compound [Cd(C(8)H(11)N(2)O(3)S)(2)](n), is a two-dimensional coordination polymer based on a Cd(2+) atom and deprotonated 2-(2-pyridylmethylamino)ethanesulfonic acid (Hpmt). The complex has molecular symmetry C (i) as a consequence of the Cd(II) being located on an inversion centre. Two N atoms of each pmt(−) ligand coordinate to the Cd(2+) ion and its sulfonate O atom bonds to an adjacent Cd(2+) ion. 24-membered (–Cd—N—C—C—S—O–)(4) rings are formed between neighbouring Cd(2+) ions; these are interconnected, forming a two-dimensional layer structure. In respect to stereogenic amino N atom and the inversion symmetry of the complex, the compound is a 1:1 racemate. The crystal packing is stabilized by intermolecular N—H⋯O hydrogen bonds and further connected by π–π stacking interactions between the pyridyl rings [average interplanar distance and centroid–centroid separation = 3.582 (1) and 3.634 (1)Å, respectively], forming a three-dimensional supramolecular architecture. |
