The first potassium amidino-guanidinate complex, -poly[[bis-(μ-1-amidinato-,','','''-tetra-iso-propyl-guanidinato-κ : , : , )dipotassium]-μ-1,2-di-meth-oxy-ethane-κ :'], [K(CHN)(CHO)] or [{ PrN= CHN( Pr)N(N Pr)K}(-DME)] where DME is 1,2-di-meth-oxy-ethane, has been synthesized and structurally characterized. The title compound was isolated in 76% yield from a reaction of ,'-diiso-propyl-carbodi-imide with potassium hydride in DME. The single-crystal X-ray structure determination of the title compound revealed a polymeric chain structure comprising cage-like dimeric units, with the amidino-guanidinate ligand displaying a mixed σ-/π-coordination mode.
首个脒基胍基钾配合物，-聚[[双-(μ-1-脒基-，'，''-四异丙基胍基-κ : ， : ， )二钾]-μ-1,2-二甲氧基乙烷-κ :']，[K(CHN)(CHO)] 或 [{ PrN= CHN( Pr)N(N Pr)K}(-DME)]，其中DME为1,2-二甲氧基乙烷，已被合成并进行了结构表征。标题化合物通过'-二异丙基碳二亚胺与氢化钾在DME中的反应以76%的产率分离得到。标题化合物的单晶X射线结构测定揭示了一种包含笼状二聚单元的聚合物链结构，其中脒基胍基配体呈现出混合的σ-/π-配位模式。
