合成了苯并15冠5冠醚配合物:[K（B15C5）2]2[Hg2（SCN）6],并通过元素分析、红外光谱及X-射线单晶结构分析进行了表征.配合物为三斜晶系、空间群P-1.晶体学数据:a=1.119 6（4）,b=1.392 6（4）,c=1.393 6（4）nm,α=70.803（4）°,β=68.992（5）°,γ=78.498（6）°,υ=1.906 3（10）nm3,z=2,Dcalc=1.656 Mg·m-3,F（000）=948,R1=0.042 8,wR2=0.114 5.配合物由两个[K（B15C5）2]+配阳离子和一个[Hg2（SCN）6]2-配阴离子组成.每个汞原子与三个SCN基团的S原子配位成键,每个汞原子另外配位位置被SCN基团N占据,这样每个汞原子通过SCN基团搭桥成键,从而形成二聚体结构.K+与2个冠醚环10个氧原子成键而形成夹心型结构.两个苯并15冠5的苯环相对钾原子呈顺式排列.
The synthesis of benzo [a] crown-5 crown ether complex [K (B15C5) 2] 2 [Hg2 (SCN) 6] was characterized by elemental analysis, IR and X-ray single crystal structure. Triclinic, space group P-1. Crystallographic data: a = 1.119 6 (4), b = 1.392 6 (4), c = 1.393 6 (4) nm, 68.992 (5) °, γ = 78.498 (6) °, ν = 1.906 3 (10) nm3, z = 2, Dcalc = 1.656 Mg · m -3, F (000) = 948, R1 = 0.042 8, wR2 = 0.114 5. Complexes consist of two [K (B15C5) 2] + cations and one [Hg2 (SCN) 6] 2-anions with each mercury atom coordinating to the S atom of the three SCN groups , Each additional atom of the mercury atom is occupied by the SCN group N such that each mercury atom bridges through the SCN group to form a dimeric structure. K + bonds to 10 oxygen atoms of the two crown ether rings Form a sandwich type structure.The benzene rings of two benzo 15 crown 5 are arranged in a cis form relative to the potassium atom.
