“…In spite of this, the ligand has a short bite with a short Cu-Cu distance of 2.786(1) Å for the phosphine bridged centers. In the analogous dppm complex, [19] the phosphine bridged Cu-Cu distance was longer by almost 0.12 Å (2.905 Å).…”

“…A combination of two factors, the diphosphinoamine to copper ratio, and the nature of the substituent on N, control the nuclearity and structure of the copper complexes in the solid state. The solid state and solution behavior for the dppan ligand system has also been compared with that of the recently reported bis(diphenylphosphino)isopropylamine (dppipa) complexes of copper(I) [19].

“…Instead, other structural motifs are often found. A ligand system introduced by Samuelson and co-workers [28] serves to understand this: their ligand, bis(diphenylphosphino)isopropyl amine, (dppipa), is quite flexible; therefore it can be a chelating as well as a bridging ligand. Due to this, mono-, di-, tri-and tetranuclear Cu I -dppipa complexes have been reported.…”

Easy come, easy go: the great structural diversity of Cu(I) complexes is an ambivalent trait. Apart from the well-known catalytic properties of Cu(I), a great number of potent luminescent complexes have been found in the last ten years featuring a plethora of structural motifs. The downside of this variety is the undesired formation of other species upon processing. In here, strategies to avoid this behavior are presented: Only one favorable structural unit often exists for multinuclear Cu(I) complexes with bridging ligands. In addition, these complexes exhibit favorable photophysical properties due to cooperative effects of the metal halide core. Furthermore, we demonstrate the broad range of applications of emitting Cu(I) compounds.

The 1 : 1 reaction between 2-(3,5-dimethylpyrazolylmethyl)-5-(diphenylphosphinomethyl)pyrrole L and CuX (X = Cl, and Br) in THF afforded the symmetrical binuclear copper(I) complexes [Cu(μ-X){μ-C 4 H 2 NH-2-(CH 2 PPh 2 )-5-(CH 2 Me 2 pz)-k 2 P,N}] 2 , having one type of copper environment. When X = I, the asymmetrical complex having two copper environments was isolated, in addition to the symmetrical complex as crystals. Interestingly, the 1 : 2 ratio reaction between L and CuCl gave a distorted cubane type complex [Cu 4 Cl 4 {μ-C 4 H 2 NH-2-(CH 2 PPh 2 )-5-(CH 2 Me 2 pz)-k 2 P,N} 2 ], while the CuBr and CuI reactions did not give similar cubane complexes. Conversely, the 2 : 1 (L : Cu) ratio reactions using CuX (X=Cl, Br and I) in THF suggest the formation of four coordinate bis-chelated copper(I) complex of the type [CuL 2 ] + in solution, in addition to the binuclear complexes. The X-ray solid state structures of [CuL 2 X 2 ] (X = Br and I) are retained in solution, in contrast to its chloride derivative giving two signals in 31 P{ 1 H} NMR spectrum. The formation of the binuclear complexes from [CuL 2 ] + and their equilibria were shown by variable temperature NMR, 31 P{ 1 H} 2D NOESY and HRMS studies. In addition, the reaction of L with [Cu(CH 3 CN) 4 ]BF 4 gave yet another binuclear complex [Cu 2 L 2 ] [BF 4 ] 2 which was characterized by spectroscopic methods. This study lends support for the hemilability of L. Figure 5. (a) Variable-temperature 1 H NMR spectra (400 MHz) of complex 4 in CDCl 3 ; (b) proposed dynamic process in solution.
