摘要：
A two-dimensional (2D) complex {[Mn-1.5(L)(bpe)(1.5)]center dot(bpe)(0.5)}(n) (1) (H3L = 3-(2-carboxy-phenoxy)phthalic acid, bpe = 1,2-bis(4-pyridyl)ethene), consisting of manganese(II) chains and bridging bpe ligands, has been synthesized and characterized. The magnetic behavior of 1 can be simulated as a -J(1)J(1)J(2)-alternating chain. Magnetic studies show that this complex magnetic behavior belongs to spin canting and exhibits an unusually high T-c around 40 K. A theoretical study based on DFT-BS calculations provides some insight into the underlying mechanism of the novel magnetic properties.
