本文报道了新化合物Sn9O5Cl4（CN 2）2的形成，并将其与最近发现的几种锡碳二亚胺化合物（Sn（CN 2）、Sn2O（CN 2）和Sn4Cl2（CN 2）3）放在一起，这些化合物都含有二价锡。Sn9O5Cl4（CN 2）2的晶体结构由X射线粉末衍射测定，包括不寻常的[Sn8O3]簇，其中锡原子形成六方双锥的图案。一个额外的锡原子和两个氧原子将这些簇连接成链。穆斯堡尔谱显示锡主要采用+2氧化态，电子结构计算预测Sn9O5Cl4（CN 2）2是半导体。
The formation of the new compound Sn9O5Cl4(CN2)2 is reported and placed in the context of several other recently discovered tin carbodiimide compounds (Sn(CN2), Sn2O(CN2), and Sn4Cl2(CN2)3), all of which contain divalent tin. The crystal structure of Sn9O5Cl4(CN2)2, as determined by X-ray powder diffraction, includes an unusual [Sn8O3] cluster, in which tin atoms form the motif of a hexagonal bipyramid. An additional tin atom and two oxygen atoms connect these clusters into chains. Mössbauer spectroscopy shows tin to predominantly adopt the +2 oxidation state, and electronic structure calculations predict Sn9O5Cl4(CN2)2 to be a semiconductor.
