研究了六种无自旋的二价钴四卤配合物CoX 4 -2（X=Cl-，Br-，I-）在一定温度范围内的磁化率，发现其磁化率符合居里-韦斯定律.磁矩被发现是在晶体场理论预测的顺序，即，I->Br->Cl-，而以前报道的这些离子的矩是在相反的方向。简要讨论了这一趋势的起源。从磁测量获得的证据提供支持的分配Ballhausen和Jorgensen和Orgel的晶场带在CoCl 4 -2。
The magnetic susceptibilities of six spin‐free tetrahalo complexes of bivalent cobalt, CoX4—2 (X=Cl—, Br—, I—), have been investigated over a temperature range and found to exhibit satisfactory dependence on the Curie‐Weiss law. The magnetic moments were found to be in the order predicted by crystal field theory, viz., I—>Br—>Cl—, whereas previously reported moments for these ions are in the reverse direction. The origin of this trend is briefly discussed. Evidence obtained from the magnetic measurements is offered in support of the assignments by Ballhausen and Jorgensen and by Orgel of the crystal field bands in CoCl4—2.
