The reaction of Tl(C5H5) with Ag[C5(CN)5] gives unexpectedly the title compound. Its crystal structure shows a dimeric [Tl2[C5(CN)2]2] forming the asymmetric unit. These units are connected to “layers” perpendicular to the a axis with formation of numerous 4-, 9- and 14 membered rings, with the Tl ions using three nitrile functions from three different ligands. These layers are connected in a direction with each Tl ion coordinating to three more nitrile functions and additional weak delocalized η5 or η3 interactions with a cyclopentadienyl ring.

聚腈的配位化学,第八部分。五氰基环戊二烯铊

Tl(C 5 H 5 )与Ag[C 5 (CN) 5 ]的反应出乎意料地得到标题化合物。其晶体结构显示形成不对称单元的二聚体[Tl 2 [C 5 (CN) 2 ] 2 ]。这些单元连接到垂直于a轴的“层” ,形成许多 4、9 和 14 元环,Tl 离子使用来自三个不同配体的三个腈官能团。这些层在一个方向上连接,每个 Tl 离子配位到三个以上的腈函数和额外的弱离域 η 5或 η 3 环戊二烯基环的相互作用。
