手性配合物模板剂对磷酸锌骨架的手性传递

Chiral Transference from the Chiral Metal Complex to the Zinc Phosphates

以外消旋的钴胺配合物Co(en)3Cl3为模板剂,在水热体系中合成出二种新颖的磷酸锌化合物:犤Co(en)3犦·犤Zn8P6O24Cl犦·2H2O(1)和犤Co(en)3犦2·犤Zn6P8O32H8犦(2)。单晶X-射线衍射结构分析表明,二种化合物中均含有手性特征的无机结构单元,手性配合物的对映体在无机主体内被有序地拆分为Δ和Λ构象。本工作研究了手性金属配合物对无机骨架的手性传递。

Using a racemic mixture of chiral metal complex CO (en) Cl-3(3) as a template, two novel zinc phosphates [Co (en) (3)] . [Zn8P6O24Cl] . 2H(2)O (1) and [Co (en) (3)](2) . [Zn6P8O32H8] (2) have been prepared hydrothermally. Single-crystal structureal analysis demonstrates that both compounds contain chiral inorganic structural motifs and that the enantiomers of the chiral complex are separated orderly as A and A configurations in the inorganic host. This work studies the chiral transference from the chiral metal complex to the inorganic framework.
