摘要：
A family of six dinuclear lanthanide complexes have been obtained via in situ hydrothermal synthesis with lanthanide ions as catalyst. These six complexes are formulated as [Ln(2)(3-Htzba)(2)(3-tzba)(2)(H2O)(8)]center dot 4H(2)O [Ln = Gd, 1; Dy, 2; Eu, 3; Tb, 4; Sm, 5; Er, 6; 3-H(2)tzba = 3-(1H-tetrazol-5-yl) benzoic acid]. The magnetic investigations show that complex 2 behaves as a single-molecule magnet (SMM) with a quantum relaxation time of similar to 10(-2) s.
