摘　　要：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.This paper reports the preparation of tiltle compounds and determination of their composition, IR spectra and the solubility behaviour of the compounds in some organic solvents. The structures of title compounds were determined by single crystal X-ray diffraction analysis. The first compound is monoclinic system and space group C2/c, two (C_6H_5)_3PO forms a dimer, [(C_6H_5)_3PO--H--OP(C_6H_5)_3]^+, in which a symmetric hydrogen bond exists. The second compound is triclinic system, and space group PI, four (C_6H_5)_3PO are connected with three hydrogens in protoned water. One of the three hydrogen bonds is branch-hydrogen bond (O—H), the other two are normal (O—H/ O).
