Synthesis of the first polymeric Cu(I) dppe (dppe=1,2-bis(diphenylphosphino)ethane) complexes

Synthesis, structure and photoluminescence of [Cu(acac)(dppe)]n with novel 1D zigzag chain-like motif

“…The copper(I) ion is tetrahedrally coordinated by two phosphorus atoms from two dppe ligands and two oxygen atoms from one acac moiety. The Cu-P distances in 1 are 2.271(1) and 2.279(1) Å, with a mean value of 2.275(1) Å, comparable with those reported in the references [14,15]. The observed Cu-O acac distances of 2.072(2) and 2.100(2) Å are longer than those Cu-O acac distances (<2.0 Å) found in other copper(I) complexes containing acac ligands, in which the copper metals are coordinated by acac and nondppe ligands [16][17][18][19][20].…”

Copper(I) complexes with Schiff base and 1,2-bis(diphenylphosphino)ethane as ligands: Synthesis, structure and catalytic properties for the amination of aryl halide

“…All of the Cu-P bond lengths are as one would expect, i.e. close to the average value (2.253 Å) found for bonds between copper and different phosphines such as those found in complex [Cu(dppe) (NO 3 )(CH 3 CN)] n [29]. The quality of data permits to distinguish between P-C (sp 2 ) and P-C (sp 3 ) bond lengths, which are 1.821-1.826 and 1.841-1.852 Å, respectively.…”

“…Copper(I) complexes containing diphosphine and N-heterocyclic ligands have been in focus of investigation in the last few years because of their interesting structures, luminescence and novel reactivity performances.The design and synthesis of Cu(I) complexes canb ei nfluencedb ym anyf actors,e specially by the ligands, anions, solvent and reaction time.The diphosphine ligands known in the literature with the general formula R 2 P-(X) n -PR 2 [X =CH 2 ,n=1-4]havebeenstudied extensively [1][2][3]. The dppm hasb een confirmed to be av erye fficient bridging bidentate ligand, and its chelating tendency is very suitable to lock two metal atomst ogether in close proximity [4].…”
