چکیده
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.

The title compound [Cu(2)(C(6)H(3)BrNO(2))(4)](n), forms sheets in the bc plane. The structure features the dinuclear paddle-wheel cage motif common to copper(II) carboxyl-ates. The polymeric structure is achieved through bridging between binuclear units by the pyridyl donors of two of the four carboxyl-ates of the cage. Each cage engages in axial bonding at each copper atom to a pyridyl nitro-...
