合成了两种基于4，6-二（2-吡啶基）-1，3，5-三嗪-2-醇（HOBPT）的钴（II）配合物[Co 3（OBPT）（μ3−OH）（SO 4）2（H2O）3]·2 H2O（1）和[Co（OBPT）2]·2 H2O（2）。单晶X射线衍射分析表明，1为二维结构，配体采用单/双齿配位，这种配位方式是以前从未发现过的。对1的磁性进行了研究，表明1是自旋斜带。与1不同的是，2是一个离散的结构，其羟基去质子化但未配位的三齿配体。2中的晶格水分子与四元水分子团簇相连，四元水分子团簇将[Co（OBPT）2]沿着B轴连接到一维链上。
Abstract Two cobalt(II) complexes based on 4,6-bis(2-pyridyl)-1,3,5-triazin-2-ol (HOBPT), [Co3(OBPT)(μ3−OH)(SO4)2(H2O)3]·2H2O (1) and [Co(OBPT)2]·2H2O (2) were obtained. Single-crystal X-ray diffraction analyses indicate that 1 is a two-dimensional (2D) structure and the ligand adopts mono/bis-bidentate coordination; this coordination mode of this ligand was never found before. Magnetic properties of 1 have been studied, showing that 1 is a spin canted belt. Much different from 1, 2 is a discrete structure with tridentate ligand with its hydroxyl group deprotonated but uncoordinated. Lattice water molecules in 2 link to four-membered water clusters, which linked the [Co(OBPT)2] to 1-D chains along the b axis.
