A dinuclear cobalt(II) complex of calix[8]arenes exibiting strong magnetic anisotropy. DALTON TRANSACTIONS (40) : 4582-4588. ScholarBank@NUS Repository. https://doi.org/10.1039/b708926k | Abstract: | The solvothermal reaction of cobalt(ii) acetate with p-tert-butylcalix[8] arene (calix) and triethylamine affords the compound (Et3NH) 2 [CoII2(calix)2] (1·2Et 3NH) that shows a hydrogen bond bridged dinuclear complex [Co II2(calix)2]2- (1) with cobalt(ii) ions in a tetrahedral geometry. The compound crystallises in the monoclinic, space group P21/n with cell parameters a = 14.89(1) Å, b = 20.90(2) Å, c = 30.87(4) Å, β = 102.57(7)°, V = 9376(16) Å3, Z = 2. The magnetic studies together with ab initio calculations are evidence of an important role of the geometry of the second coordination sphere of carbon and hydrogen atoms around the CoO4 core in quantifying the zero field splitting on cobalt sites. This results in strong magnetic anisotropies with a negative axial component on the cobalt fragments. © The Royal Society of Chemistry. | Source Title: | DALTON TRANSACTIONS | URI: | https://scholarbank.nus.edu.sg/handle/10635/228679 | ISSN: | 14779226 14779234 |
