Abstract: The title polymer, [Cu(C₈H₁₁N₂O₃S)(SCN)]_n or [Cu(PMT)(SCN)]_n, contains six-coordinate Cu^II units. The Cu^II ion is coordinated by one thiocyanate N atom, an N,N',O-tridentate 2-(2-pyridylmethylamino)ethanesulfonate (PMT) anion and two axial bridging sulfonate O atoms from two adjacent PMT ligands in a distorted octahedron. The deprotonated PMT ligand acts as a ₃-bridging ligand and forms an eight-membered (-Cu-O-S-O-)₂ ring between two neighbouring Cu^II atoms. These rings are interconnected, generating a one-dimensional linear chain structure. These polymetric chains are connected into a three-dimensional network via interchain - stacking of the pyridine rings and intermolecular hydrogen bonds.
