Ag(i) complexes with alkylidene-bis(2-aminopyrimidines) as building units for discrete metallomacrocyclic frames. A structural and solution study
摘要:
烯叉双(2-氨基嘧啶)(pyr2Cx, x = 2–5)是有用的配体,能与Ag(I)生成离散的金属环。分离得到了[(pyr2C2)Ag(NO3)]2和[(H-pyr2C4)Ag(NO3)2]2的晶体结构,其中每个大环部分都通过弱相互作用与其周围环境相互作用,形成三维离散结构。另一方面,溶液研究显示,Ag(pyr2Cx)+配合物的形成平衡常数高于已知文献中单嘧啶Ag(I)配合物的值,尽管这种差异可以通过考虑Ag(I)-pyr2Cx配合物的固态结构来解释。

Alkylidene-bis(2-aminopyrimidines)
(pyr2Cx, x
= 2–5) are useful ligands to interact with Ag(I) yielding discrete metallocycles. Crystal structures of the [(pyr2C2)Ag(NO3)]2 and [(H-pyr2C4)Ag(NO3)2]2 have been isolated where each macrocyclic moiety interacts with their surroundings through weak interactions, yielding 3D discrete structures, On the other hand, the solution study shows that the equilibrium constants for the formation of Ag(pyr2Cx)+ complexes are higher than the literature values for Ag(I) complexes with single pyrimidines, although the differences could be explained by invoking the solid-state structures of the Ag(I)–pyr2Cx complexes.
