The employment of the new Schiff base ligand 2-[(4-chloro-2-hydroxybenzylideneamino)methyl]phenol (HL) bearing ON donors for the preparation of a novel Co cluster is reported. The hexanuclear cobalt complex, namely, di-μ-acetatotetrakis{μ-2-[(4-chloro-2-oxidobenzylideneamino)methyl]phenolato}tetra-μ-methanolato-tetracobalt(II)dicobalt(III), [CoCo(CHClNO)(CHCOO)(CHO)], was obtained using Co(CHCOO)·4HO and HL as starting materials in MeOH under solvothermal conditions. The six metal ions are linked together by the μ-O atoms of four deprotonated MeOH molecules, two CHCOO units and six phenolate O atoms of four L ligands to form a defect disk-shaped topology. DC magnetic susceptibility investigations revealed the existence of antiferromagnetic interactions in the Co cluster.
报道了使用含ON供体的新型席夫碱配体2-[(4-氯-2-羟基亚苄基氨基)甲基]苯酚（HL）制备新型钴簇合物。以Co(CH₃COO)₂·4H₂O和HL为原料，在甲醇溶剂热条件下得到了六核钴配合物，即二-μ-乙酸根四{μ-2-[(4-氯-2-氧化亚苄基氨基)甲基]苯酚根}四-μ-甲醇根-四钴(II)二钴(III)，[Co₆Co₂(CHClNO)₂(CH₃COO)₂(CH₃OH)₄]。六个金属离子通过四个去质子化甲醇分子的μ-O原子、两个CH₃COO单元以及四个L配体的六个酚盐O原子连接在一起，形成了一种缺陷盘状拓扑结构。直流磁化率研究表明该钴簇合物中存在反铁磁相互作用。
