title: catena-Poly[copper(II)-bis-(μ-3-cyano-2-hydroxy-propionato)-κN:O,O;κO,O:N-copper(II)].
abstract: The title compound, [Cu(C(4)H(4)NO(3))(2)](n), exhibits a double-chain structure extending along [100]. The Cu(II) atom, lying on an inversion center, is coordinated by two cyano N atoms from two 3-cyano-2-hydroxy-propionate ligands and two hydr-oxy O atoms and two carboxyl-ate O atom from two other two ligands in a distorted octa-hedral geometry. Inter-molecular C-H⋯O and O-H⋯O hydrogen bonds connect the chains into a three-dimensional structure.
