本文报道了三苯基氧化膦与氯金酸形成的两种配合物晶体的合成、特性和结构.由元素分析及谱学特性确定了萃合物的组成分别为HAuCl_4·2(C_6H_5)_3PO(1)和HAuCl_4·H_2O·4(C_6H_5)_3PO(2).X射线结构分析确定了两种单晶的结构.晶体(1)属于单斜晶系,空间群为C2/c,组成化学式为[(Ph_3PO)_2H]·AuCl_4,其中存在有对称氢键.晶体(2)属于三斜晶系,空间群为PI,组成化学式为(H_3O)·[AuCl_4]·4Ph_3PO,其中存在有分叉氢键.
In this paper, the synthesis, characterization and structure of two crystal complexes of triphenylphosphine oxide and chloroauric acid were reported.The composition of the complex was determined as HAuCl_4 · 2 (C_6H_5) _3PO ( 1) and HAuCl_4 · H_2O · 4 (C_6H_5) _3PO (2) .According to the X-ray structure analysis, the structures of two kinds of single crystals were determined. The crystal belongs to the monoclinic system with C2 / c space group and the chemical formula is [ (Ph_3PO) _2H] · AuCl_4, in which symmetrical hydrogen bonds exist.The crystal (2) belongs to the triclinic system with space group PI and its composition formula is (H_3O) · [AuCl_4] · 4Ph_3PO, .
