Combined EXAFS and DFT Structure Calculations Provide Structural Insights into the 1:1 Multi‐Histidine Complexes of CuII, CuI, and ZnII with the Tandem Octarepeats of the Mammalian Prion Protein

“…For example, bis(2-methylbenzimidazole)-copper(I) (ETERIE) is a linear complex with CuÀN bond lengths of 1.874 . [44] The EHEPOX small-molecule crystal structure contains numerous co-crystallized bis(imidazole)-copper(I) complexes displaying a range of CuÀN bond lengths with an average of 1.86 AE 0.03 . [45] Our DFT-optimized structure has the Ne-Cu-Ne angle very nearly linear (179.68), in good agreement with the various crystal structure examples, and our calculated Cu-Ne bond length is 1.89 .…”

“…There are numerous examples of digonal Cu + complexes bound by imidazole‐type ligands in the Cambridge Structure Database. For example, bis(2‐methylbenzimidazole)‐copper(I) (ETERIE) is a linear complex with CuN bond lengths of 1.874 Å 44. The EHEPOX small‐molecule crystal structure contains numerous co‐crystallized bis(imidazole)‐copper(I) complexes displaying a range of CuN bond lengths with an average of 1.86±0.03 Å 45.…”

Synthesis and characterization of the 1:1 adducts of copper(I) halides with bidentate N,N′-bis(benzophenone)-1,2-diiminoethane Schiff base: Crystal structures of [Cu(bz2en)2][CuX2] (X=Br, I) complexes

“…The number of ligands bound to the monovalent copper ion is influenced greatly by both the chemical nature and geometry of ligand L and the type of halogen X [13]. Although structural reports on [Cu I (N 4 )] + complex cations are numerous [10][11][12][13][14][15][16][17][18][19], there are a limited number of studies on the copper(I) complexes with isolated linear dihalogenocuprate(I) anions [20][21][22][23][24]. The structures of halogenocuprate(I) compounds are exceptionally varied, and the degree of dilution imposed on the ligands by the cation plays an important role in determining the coordination number of Cu(I) in halogenocuprates and the tendency of the anions to form extended structures [25][26][27][28][29][30].…”

Electrochemical Synthesis and Structural Characterization of a Novel Mixed-valence Copper (I)-copper (II) Complex: {[Bis(ethylenediamine) Copper (II)] Bis[diiodocuprate (I)]}

“…Although to date remarkable Cu(I) complexes [8][9][10][11] and examples of Cu(I) complexes with halocuprate anion [12][13][14] have been reported, there is no report on diiodocuprate (I) anion polymeric complex with ethylenediamine. Thus, we report herein the electrosynthesis and crystal structure of a novel Cu(I) polymeric complex with potentiostatic dissolution of copper anode in a solution of ethylendiamine and iodine in AcN.…”
