本文合成了高氯酸钴(Ⅱ)与内、外消旋的双(正—丙基亚砜)乙烷的两个固体配合物;[Co(α-bprse)_3](ClO_4)_2·H_2O及[Co(β-bprse)_2(H_2O)_2](ClO_4)_2·H_2O(α-bprse和β-bprse分别表示外和内消旋的C_3H_7S(O)(CH_2)_2S(O)C_3H_7)。由元素分析、红外光谱、核磁共振谱、磁化率和电导等研究,指明两个固体配合物是以氧原子配位的高自旋、畸变八面体配合物,配位数为6。从合成条件及配位场参数Dq的计算说明双(正—丙基亚砜)乙烷对钴(Ⅱ)是比水还弱的配体。
In this paper, two solid complexes of cobalt (II) perchlorate with bis (n-propylsulfoxide) ethane were synthesized. [Co (α-bprse) _3] (ClO_4) _2 · H_2O And [Co (β-bprse) _2 (H_2O) _2] (ClO_4) _2 · H_2O (α-bprse and β-bprse represent exo and meso C_3H_7S (O) (CH_2) _2S (O) C_3H_7, respectively). The results of elemental analysis, IR, NMR, magnetic susceptibility and conductivity indicate that the two solid complexes are highly spinodized and octahedral complexes coordinated by oxygen atoms with a coordination number of 6. The synthesis conditions and the coordination field parameter Dq indicate that bis (n-propyl sulfoxide) ethane is a weaker ligand than cobalt for cobalt (II).
