In the title complex, [Zn(CFOS)Cl(CHClN)]·CHCN, the zinc(II) core is fivefold coordinated by one chloride, one tri-fluoro-methane-sulfonate O atom and three terpyridine N atoms in a slightly distorted square-pyramidal geometry. The structure provides a distinct example amongst other zinc(II) 4-chloro-terpyridine complexes because of the unusual planarity of the coordinated chloride, the short length of the Zn-N bond opposite to the chloride ligand [1.9572 (15) Å], and the presence of an elongated Zn-O bond [2.3911 (14) Å] in the coordinated tri-fluoro-methane-sulfonate ion. A molecule of acetonitrile is also found in the asymmetric unit of the title complex.
在标题配合物[Zn(CFOS)Cl(CHClN)]·CHCN中，锌(II)中心由一个氯离子、一个三氟甲磺酸根O原子和三个三联吡啶N原子以略微扭曲的四方锥几何构型进行五配位。该结构在其他锌(II) 4-氯三联吡啶配合物中是一个独特的例子，这是因为配位氯离子具有不寻常的平面性、与氯配体相对的Zn-N键较短[1.9572 (15) Å]以及配位三氟甲磺酸根离子中存在拉长的Zn-O键[2.3911 (14) Å]。在标题配合物的不对称单元中还发现了一个乙腈分子。
