A predesigned 1D chain of alternating di-μ1,1-azido bridged dinuclear Ni(II) and pyrazine: Synthesis, structure and magnetic properties
چکیده انگلیسی


• A unique 1-D polynuclear chain of Ni(II)
• Dinuclear di-μ1,1-azido bridged building blocks are connected through pyrazine spacer.
• Exhibits a dominant ferromagnetic exchange interaction

A new Ni(II) complex, [Ni2(L)2(μ1,1-N3)2(pyz)]n (1) (where pyz = pyrazine) has been synthesized using a dinuclear di-μ1,1-azido bridged Ni2 molecular building block derived from a tridentate NNO donor Schiff base ligand, HL (2-[(3-methylamino-propylimino)-methyl]-phenol) along with pyrazine as spacer. Single crystal X-ray analysis shows that complex 1 is a 1D chain in which dimeric Ni2 units [Ni2L2(N3)2] are linked to each other by the bridging pyrazine ligand. Variable-temperature magnetic susceptibility studies indicate the presence of moderate ferromagnetic exchange coupling in complex 1 with J value of 53.54 cm− 1.

A new ferromagnetic 1-D polynuclear chain of Ni(II) has been derived by joining dinuclear di-μ1,1-azido bridged nodes with pyrazine spacer.Figure optionsDownload as PowerPoint slide
