摘要：
A rare lanthanide-containing azametallacrown with structural formula [Er-4(mu(3)-OH)(2)(ppt)(4)(H(2)ppt)(2)(OAc)(2)]center dot 2DMF (1) (H(2)ppt = 3-(2-hydroxyphenyl)-5-(pyrazin-2-yl)-12,4-triazole) has been reported. X-ray crystallographic analysis exhibits a remarkable aza10-MC-4 structural motif with the ring having [Er-N-N-Er-O] connectivity. Measurements of dc magnetic susceptibility and isothermal magnetization reveal the strong magnetic anisotropy, and ac susceptibility shows slow magnetization relaxation at a dc field of 2000 Oe.
