摘要 以AgBF4和1,2-双正丁基硫醚乙烷(bbte)为原料,合成了一种配合物Ag(bbte)BF4晶体,对其进行了元素分析、红外光谱表征和X-射线单晶衍射测定。X射线单晶衍射显示在[Ag(bbte)BF4]n中Ag(I)处于平面三角形配位环境,bbte以两个S原子螯合一个Ag(I),其中一个S原子桥联相邻的两个Ag(I)而形成一维链状结构。该配位聚合物属单斜晶系,P2(1)/c空间群,晶胞参数为:a=0.932(1)nm,b=0.799(1)nm,c=2.181(1)nm,β=97.671(9)°,单胞体积V=1.610 8(14)nm3,晶胞内分子数Z=4,理论密度dc=1.654 Mg/m3,吸收系数μ=1.531 mm-1,(000)点结构因子F(000)=808,残差因子R1=0.069 1,wR2=0.137 8。 A one-dimensional silver (Ⅰ) complex, Ag (bbte) BF4, has been formed from AgBF4 and 1,2-bis ( n- butylsulfanyl) ethane (bbte, C,)H22 S2 ). The complex was characterized by elemental analysis and IR spectroscopy. The X-ray structure of Ag(bbte)BF4 is a chain coordinative polymer involving trigonal [ (μ2-S)2, S] ligation with one S-donor bridging two adjacent Ag(Ⅰ) centers while the other S-donor of the bbte ligand is non-bridging. The crystal belongs to monoclinic crystal system and P2(1)/c space group. Crystallographic data: a=0.932(1) nm, b =0.799(1) nm, c =2.181(1) nm,/3=97.671(9)°, V= 1.610 8(14) nm^3,Z=4, d,. = 1.654 Mg/m^3 ,μ = 1.531 mm^-1 , F(000) = 808, R1 = 0.069 1, wR2= 0.137 8.
