Di-μ-iodo-bis[(3-cyanopyridine-κN)copper(I)]

Abstract

The CuI atom in the centrosymmetric title compound, [Cu2I2(C6H5N)4], shows tetrahedral coordination; the I atom functions as a μ2 bridge.

A Codeposition Route to CuI−Pyridine Coordination Complexes for Organic Light-Emitting Diodes

“…A complex related to model B1 could also be eliminated as a possibility by comparison of the Cu−Cu and Cu−I coordination numbers in Table . The structural parameters for model D closely match those reported in the literature for model E . Thus, on the basis of both the luminescence spectra and XAS studies, the emitting species in CuI:mCPy thin films is most likely the dimeric complex [CuI(mCPy) 2 ] 2 (illustrated in the Figure inset), with small variable amounts of [CuI(mCPy)] ∞ in low enough concentration that it does not contribute significantly to the XAS.…”

“…The structural parameters found in Model D closely match those reported in the literature for [CuI(pyCN) 2 ] 2 (model E ). 27 Thus, on the basis of both the luminescent spectra and XAS studies, the emitting species in CuI:mCPy thin films is most likely a dimeric complex, [CuI(mCPy) 2 ] 2 , illustrated in the insert to Figure 5, and small variable amounts of [CuI(mCPy)] ∞ , in low enough concentration that it does not contribute significantly to the XAS.…”

“…The Fourier transform (FT) is shown in Figure , and the EXAFS fit parameters are given in Table . Table also gives EXAFS fit parameters for polymeric model complex A and related parameters (derived from crystallographic coordinates) for model B1 and [CuI(pyCN) 2 ] 2 (pyCN = 3-cyanopyridine) (model E ) for comparison. The combination of one Cu−Cu and two Cu−I paths around 2.6 Å gave the best fit to the data.…”

Di-μ-iodo-bis{[N,N-bis(diphenylphosphinomethyl)-2-pyridinamine-κ2P,P′]copper(I)} dichloromethane solvate

“…A large number of cuprous halide clusters with photoluminescence with different emissive behavior have been found (Ford et al, 1999). Copper(I) complexes bridged by I atoms, forming a dimeric entity, have been widely studied (Kickelbick et al, 2002;Huang & Ng, 2004). Recently, we have synthesized a new binuclear copper(I)-iodide complex, (I), with N,N 0 -bis[(diphenylphosphino)methyl]-2-pyridinamine as ligand.…”
