合成了二苯并18冠6冠醚配合物:[K（DB18C6）]2[Co（NCS）4]C3H6O,并通过元素分析、红外光谱及X-射线单晶衍射对结构进行了分析.配合物为:单斜晶系、空间群C2/C.晶体学数据:a=2.051（8）,b=1.517 4（7）,c=1.912 5（8）nm,β=92.422（8）°,V=5.927（4）nm3,Z=4,Dcalc=1.352 g·cm-3,F（000）=2 516,R1=0.061,wR=0.126 5.配合物由两个[K（DB18C6）]+配阳离子、一个[Co（NCS）4]2-配阴离子和一个C3H6O分子组成.四个硫氰酸根的氨原子与钴原子配位,[Co（NCS）4]2-为四面体构型.K+除与冠醚环6个氧原子成键外还与丙酮氧原子配位成键. The structure of [K (DB18C6)] 2 [Co (NCS) 4] C3H6O was synthesized and its structure was characterized by elemental analysis, IR and X-ray single crystal diffraction. The crystallites are: monoclinic, space group C2 / C. The crystallographic data are: a = 2.051 (8), b = 1.517 4 (7), c = V = 5.927 (4) nm3, Z = 4, Dcalc = 1.352 g · cm-3, F (000) = 2 516, R1 = 0.061, wR = 0.126 5. The complex consists of two [K (DB18C6) With a cation, a [Co (NCS) 4] 2-anions and a C3H6O molecule.The four thiocyanate-bearing ammonia atoms coordinate to the cobalt atom, and [Co (NCS) 4] 2- is a tetrahedral configuration. K + addition to the crown ether ring 6 oxygen atoms bond with the acetone oxygen atoms coordinate bond.
