Abstract

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 CoII 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.
