A one-dimensional cobalt(II) coordination polymer, [Co(btm)2(SCN)2·H2O]n [btm = bis(1H-1,2,4-triazol-1-yl)methane], was synthesized and magnetically characterized. The isolated slightly distorted octahedral Co(II) ion displays field-induced slow relaxation with a big positive axial and a negative rhombic magnetic anisotropy (D = 93.9 cm(-1) and E = -10.5 cm(-1)), and the anisotropy energy barrier is 45.4 K.
合成了一种一维钴（II）配位聚合物[Co(btm)2(SCN)2·H2O]n [btm = 双（1H-1,2,4-三唑-1-基）甲烷]，并对其进行了磁性表征。分离出的稍有畸变的八面体Co（II）离子表现出由磁场诱导的缓慢弛豫，具有较大的正轴向和负菱形磁各向异性（D = 93.9 cm(-1)，E = -10.5 cm(-1)），各向异性能垒为45.4 K。
