与碱金属及碱土金属相比,过渡金属冠醚配合物的报道较少,但近年来这类研究已日益引起人们的兴趣。而其结构研究是一重要方面,就第一过渡系列的d区元素而言,仅有钒(Ⅳ),锰(Ⅱ)和钴(Ⅱ)的18-冠-6配合物的报道。从立体化学考虑,我们在研究了二价过渡金属离子后,又选择了条件相似的三价铬离子。本文报道标题配合物的单晶X射线结构分析,并基于分析结果,对分子的结构特点和晶胞中的堆积方式进行了讨论。
Compared with alkali metals and alkaline earth metals, transition metal crown ether complexes reported less, but in recent years such research has increasingly attracted people’s interest. The structural study is an important aspect. For the d-region elements of the first transition series, only 18-crown-6 complexes of vanadium (IV), manganese (II) and cobalt (II) are reported. From the perspective of stereochemistry, we studied the divalent transition metal ions, we chose a condition similar to the trivalent chromium ions. This paper reports the single crystal X-ray structure analysis of the title complex and based on the results of the analysis, the structural features of the molecules and the packing patterns in the unit cell are discussed.
