| 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. |
