Triphenylphosphane complexes of copper(I): Structural and 31P NMR investigations

Syntheses And Structural Characterizations Of Heterometallic Copper(I)/Indium(Iii) Complexes Containing Phosphine Ligands

“…The 31 P NMR resonance of δ = −10.3 ppm for complex 1 is in good agreement with the resonance of [(dppeCuCl) 2 (µ-dppe)] (δ = −10.5 ppm) [14], while the 31 P NMR resonance of δ = −2.63 ppm for complex 2 is slightly down-shifted by comparison with the resonance of [Cu(PPh 3 ) 2 Cl] (δ = −3.6 ppm) due to the variation of the copper(I) coordination [15]. Both 31 P NMR spectra of complexes 1 and 2 at r. t. exhibit a broad signal (width ca.…”

“…The terminal chloride atom occupies the apical position. The heterometallic four-membered InCl 2 Cu rings in 2 are nearly planar, which is typical of the geometry in MCl 2 M rings [15,17,18]. Each ring contains a pair of long and short In-Cl and Cu-Cl bonds: In(1)-Cl(2) = 2.5228 (7) and Cu(1)-Cl(3) = 2.5692(7) ("long"), In(1)-Cl(3) = 2.4311 (7) and Cu(1)-Cl(2) = 2.4293(9)Å ("short") in the In1-Cl2-Cu1-Cl3 ring, In(1)-Cl(4) = 2.5361 (7) and Cu(2)-Cl(5) = 2.6642(8) ("long"), In(1)-Cl(5) = 2.4208 (7) and Cu (1) (1) bond length [2.3595(9)Å] in 2 is slightly longer than those in 1 [av.…”

“…cation with one terminal chloride function converted to a bridging one. Similarly, anhydrous InCl 3 was dissolved in a THF solution of CuCl and PPh 3 in a 1 : 2 ratio, in which the complex [Cu(PPh 3 ) 2 Cl] is present [15], to give complex 2 (eq. (3)).…”

Reactivity of Cu(I) Compounds towards Ethylenediamine and Dimethylformamide: Crystal Structure of CuCl(PiPr3)n (n=1, 2), CuX(PPh3)(en)2 (X=Cl, Br) and CuX(PPh3)(dmf)

“…2). The copper atom is coordinated by one Cl atom and two P atoms in an almost ideal trigonalplanar arrangement which was also found for numerous other complexes of the general formula CuCl(PR 3 ) 2 with large groups R [22,31,32]. The CuCl distance is 2.2592(6)Å, and the Cu-P distances amount to 2.2419(6) and 2.2652(6)Å.…”

Ruthenium(II), copper(I) and silver(I) complexes of large bite bisphosphinite, bis(2-diphenylphosphinoxynaphthalen-1-yl)methane: Application of Ru(II) complexes towards the hydrogenation of styrene and phenylacetylene

“…The structure of complex 4 is similar to that of (PPh 3 ) 2 CuCl [9]. The P1-Cu-P2 bite angle in complex 4 is very large compared to 0.12 · 0.14 · 0.14 0.09 · 0.14 · 0.18 Space group P21/n (No.…”
