1D coordination polymer with octahedral and square-planar nickel(II) centers

Synthesis of an interesting Ni(II) 1D-chain, [Ni3(ashz)2(DMF)2(H2O)2]n·4DMF (1·4DMF), derived from N-acetylsalicylhydrazide (H3ashz) has been reported. The unprecedented bridging coordination mode involving the phenoate oxygen of ashz3 − leads to the formation of a polynuclear 1D-chain without any additional spacer ligand. The coordination polymer 1 contains the Ni(II) cations in octahedral and in square-planar environments and shows antiferromagnetic interactions.
