dc.description.abstractThe synthesis, crystal structure, electrochemical and magnetic properties of a type of pyridine-modulated linear pentanuclear complex, [Ni-5(mu-dmpzda)(4)(NCS)(2)] [dmpzda-H-2=N,N'-di(4-methyl pyridin-2-yl)pyrazine-2,6-diamine], were studied. The complex involves a Ni-5 linear chain unit with all of the Ni-Ni-Ni being nearly 180 degrees, terminated by the two axial ligands. This pentanuclear linear metal chain is helically wrapped by four syn-syn-syn-syn type dmpzda ligands. There are two types of Ni-Ni distances existing in the complex. The terminal Ni-Ni distances bonded with the axial ligand are longer (2.3821 angstrom) affected by the axial ligands. The inner Ni-Ni distances are very short and remain constant (2.2959 angstrom). Two terminal Ni(II) ions bonded with the axial ligands are in a square-pyramidal (NiN4NCS) environment and exhibit long Ni-N bonds (2.103 angstrom), which are consistent with a high-spin Ni(II) configuration. The inner three Ni(II) ions display short Ni-N (1.886-1.906 angstrom) bond distances, which are consistent with a squareplanar (NiN4), diamagnetic arrangement of a low-spin Ni(II) configuration. This compound exhibits similar [Ni-5(mu-tpda)(4)(NCS)(2)] magnetic behavior, indicating an antiferromagnetic interaction of two terminal high-spin Ni(II) ions in these complexes.en_US
