摘要：
A new 1-D helical chain complex [Cu(H2L)(SO4)]center dot CH3OH (1) (H2L = N,N-bis(3,5-dimethyl-2-hydroxybenzyl)-N-(2-pyridylmethyl)amine) was synthesized from the reaction of the tripodal tetradentate ligand H2L with CuSO4 center dot 5H(2)O under solvothermal conditions. Complex 1 was fully characterized by X-ray single crystal diffraction, elemental analysis and IR spectroscopy. X-ray analysis revealed that complex 1 displays a 1-D helical chain structure with the two adjacent metals being bridged by a sulfate ion. Each Cu-II ion is penta-coordinated and exhibits a pseudo square pyramidal geometry. The low-temperature magnetic susceptibility measurement for the solid sample of 1 revealed the ferromagnetic Cu-II center dot center dot center dot Cu-II interactions. (C) 2012 Elsevier B.V.
