合成了具有一定空阻的配体α-萘硫酚及其铜的配合物[α-C_(10)H_7SCu]_n.它在PPh_3存在下与CS_2反应,获得了CS_2在其Cu—S键中的插入产物,用X射线衍射法测得其晶体结构为[(Ph_3P)_2Cu(α-C_(10)H_7SCS_2)]·CS_2(1).由此单核插入产物与混合溶剂CH_2Cl_2/CH_3OH反应,培养出产物的晶体,测定结构为(Ph_3P)_2Cu(α-C_(10)H_7S)_2Cu(PPh_3)(2).化合物(1)是以铜原子为中心的配合物,铜原子以变形四面体与流代黄原酸α-C_(10)H_7SCS_2~-的两个S原子和两个Ph_3P的P原子配位.化合物(2)为中性双核铜配合物,2个萘硫酚配体的硫原子桥连2个铜原子,组成了四边形.2个铜原子配位情况不同,Cu(1)采用平面三配位构型,分别与2个桥连的硫原子和1个PPh_3的磷原子配位,而Cu(2)则与2个桥连的硫原子和2个PPh_3的磷原子形成变形四面体配位.
The [α-C_ (10) H_7SCu] _n, a ligand of α-naphthalenethiol and its copper with a certain air resistance, was synthesized and reacted with CS_2 in the presence of PPh_3. The crystal structure of the product was [(Ph_3P) _2Cu (α-C_ (10) H_7SCS_2)] · CS_2 (1) as measured by X-ray diffractometry.The single-nucleophilic insertion reaction with CH_2Cl_2 / CH_3OH, The crystal of the product was obtained and its structure was determined to be (Ph_3P) _2Cu (α-C_ (10) H_7S) _2Cu (PPh_3) (2) Compound (1) is a copper atom-centered complex, Which is coordinated with two S atoms of α-C_ (10) H_7SCS_2 ~ - and two P_3P atoms of the xanthogenate X. Compound (2) is a neutral dinuclear copper complex and two thionaphthol ligands The sulfur atom bridges two copper atoms and forms a quadrilateral pattern. The coordination of the two copper atoms is different. Cu (1) adopts a planar three-coordinate configuration and is respectively connected with two bridged sulfur atoms and one PPh_3 phosphorus atom While Cu (2) forms a distorted tetrahedron with two bridged sulfur atoms and two PPh_3 phosphorus atoms.
