Abstract

Source of materialThesynthesis of thetitlecompoundwas carried out by stirring the mixture of CuSCN (0.0594 g, 0.3m mol), bis(diphenylphosphino)methane (dppm,0 .1154 g, 0.3m mol) and 1,10-phenanthroline (1,10-phen, 0.05645 g, 0.3 mmol) in 5m lo f CH 3 CN and 5mlofCH 2 Cl 2 for 6hours at room temperature. The filtrate wasallowed to standatthe room temperature. Slow evaporation of thesolventyielded yellow crystals. Experimental detailsTheratio N gt /N(param) is low because good quality single crystals of this compound are difficult to grow and hence the collection of data at room temperature is achallenge. DiscussionCopper(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]. The Nheterocyclic 1,10-phen is an efficient chelating ligand.
