摘要：

A new dinuclear cobalt(II) complex [Co2L2Cl2(CH3OH)(2)] (1), where HL = 3-[(furan-2-ylmethylimino) methyl]-2-hydroxy-5-methylbenzaldehyde, derived from the in situ condensation of 2,6-diformyl- 4-methylphenol with furfurylamine, was prepared and structurally and magnetically characterized. Single crystal X-ray structural determination reveals that the structure consists of centrosymmetric dinuclear units with each Co-II ion in a slightly distorted octahedral environment. Lines' model, which in principle can theoretically separate in spin-only and orbital contribution, was used to fit the variable temperature susceptibility (2-300 K), suggesting an intramolecular antiferromagnetic interaction between the cobalt(II) ions.
