Herein we study the structures of selected 2,9-disubstituted and 2-monosubstituted phenanthroline Ni-dibromido and diiodido complexes via SC-XRD, SQUID magnetometry, UV-vis-NIR and DOSY NMR. In spite of the divergent speciation in solid state and in DMF solution, the Ni-dibromido complexes of both mono- and disubstituted phenanthrolines converge to monomeric species in both THF and CDCl. On the other hand, the nickel iodide complexes remain as monomers both in solid state and in solution, regardless of ligand substitution patterns.
在此,我们通过单晶X射线衍射(SC-XRD)、超导量子干涉仪磁力测定法(SQUID magnetometry)、紫外-可见-近红外光谱(UV-vis-NIR)和扩散排序核磁共振谱(DOSY NMR)研究了选定的2,9-二取代和2-单取代菲咯啉镍二溴化物和二碘化物配合物的结构。尽管在固态和N,N-二甲基甲酰胺(DMF)溶液中的物种形成不同,但单取代和二取代菲咯啉的镍二溴化物配合物在四氢呋喃(THF)和氯仿(CDCl₃)中均收敛为单体物种。另一方面,无论配体取代模式如何,碘化镍配合物在固态和溶液中均保持为单体。
