New heteronuclear gold(III)–mercury(II) compounds are synthesized by the chemisorption reaction of freshly precipitated mercury dimethyl (MeDtc) and diethyl dithiocarbamates (EtDtc) with [AuCl4]− anions in a medium of 2 M HCl. The crystals of complexes [AuS2CN(CH3)2}2]2[HgCl4] (I) and ([AuS2CN(C2H5)2}2]2[Hg2Cl6] • OC(CH3)2) n (II) are obtained from solutions in methanol and acetone, respectively
在2 M HCl介质中,新沉淀的二甲基汞(MeDtc)和二乙基二硫代氨基甲酸酯(EtDtc)与[AuCl 4 ] -阴离子的化学吸附反应合成了新的异核金(III)-汞(II)化合物。配合物[Au S 2 CN(CH 3)2 } 2 ] 2 [HgCl 4 ](I)和([[Au S 2 CN(C 2 H 5)2 } 2 ] 2 ] 2 [Hg 2 Cl 6 ]•OC(CH 3)2)n (II)分别从甲醇和丙酮溶液中获得。通过X射线衍射分析(CIF文件,CCDC号1452118(I)和1452119(II))确定制备分离的化合物的晶体和超分子结构。离子配合物I的结构由交替的双核[Au 2 S 2 CN(CH 3)2 } 4 ] 2+阳离子和[HgCl 4 ] 2-阴离子构成。化合物II的更复杂结构包含中心对称异构体[Au S 2 CN(C 2H 5)2 } 2 ] +阳离子(A和B)和中心对称的双核[Hg
