Abstract: A new one-dimensional coordination polymer, catena-poly[[aqua(nitrato-²O,O')copper(II)]--pyrazine-2-carboxylato- ³N¹,O:N⁴], [Cu(C₅H₃N₂O₂)(NO₃)(H₂O)]_n, has been synthesized and characterized. The coordination environment of the copper(II) ion is distorted octahedral, arising from an N,O-bidentate 2-pyrazinecarboxylate ligand, an N atom from a symmetry-related 2-pyrazinecarboxylate ligand, a bidentate nitrate group and a water molecule. The chains interact by way of O-HO hydrogen bonds and C-HO interactions.
