A novel 3D Co(II) coordination polymer with a considerable 2D channel: Synthesis, topological structure, magnetic and electrochemical properties

A novel 3D Co(II) complex [Co(Hhmt)(H2O)∙H2O] (1) (H3hmt = 3,5-bis (hydroxymethyl)-1,2,4-triazole) has been hydrothermally synthesized. X-ray single crystal diffraction experiment reveals that each Hhmt2 − ligand connects three Co(II) ions to form a 3D lvt topological framework with the (42 ∙ 84) point symbol, especially for the existence of a considerable 2D channel. The magnetic and electrochemical properties of 1 are also discussed.
