“…The two Cu atomsa re bridged by Pa toms from dppm ligand. The structure is similar to that of {[Cu 2 (dppe) 2 (phen) 2 ] (ClO 4 ) 2 (CH 2 Cl 2 )} n (1) [ 5], but different from {[Cu 2 (dppm) 2 (BF 4 ) 2 (pyz)](CH 2 Cl 2 ) 2 } n (2) [ 5]. d(Cu-P) =2 .194(2)-2.212(2) Åa re shorter than the corresponding distances in (1) (2.212(6)-2.266(1) Å) and (2)( 2.224(2)-2.227(2) Å).F urthermore, d(Cu-N) =1.945(5)-2.134(5) Åinthe title complex are different from the corresponding distances in (1)( 2.070(1)-2.120(1) Å) and in (2)( 2.091(4) Å).The difference of the distances in the three similar complexes above is due to the difference of the nitrogen heterocycle ligands, anions and solvents in them.…”

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.

“…During our previous work, a number of mixed-ligand coordination compounds of copper(I) salts with heterocyclic nitrogen ligands and diphosphanes were prepared and structurally characterized [6,7]. Among numerous multi-functional ligands, 1,4-bis(diphenylphosphino)butane(dppb) is a good ligand candidate because its bridging ability is very suitable to lock two Cu(I) atoms together to form a Cu 2 (dppb) core structure.…”

C 58 H 56 Cu 2 N 6 O 2 P 2 , monoclinic, P21/n, a = 12.0546(9) Å, b = 13.1669(10) Å, c = 16.7151(12) Å, β = 101.845(2)°, CCDC no.: 1543452 The crystal structure (water molecular removed) is shown in the figure. Tables 1 and 2 contain details on crystal structure and measurement conditions and a list of the atoms including atomic coordinates and displacement parameters. Source of materialA mixture of CuCN (0.0179 g, 0.2 mmol), 2,9-dimethyl-1,10-phenanthroline (dmp) (0.0434 g, 0.2 mmol) and 1,4-bis(diphenylphosphino)butane (dppb) (0.0853 g, 0.2 mmol) were dissolved in a mixture of CH 3 CN and CH 2 Cl 2 (10 mL, v/v = 1:1). After being stirred for 6 hours at room temperature, the liquid was filtered. Subsequent slow evaporation of the filtrate resulted in the formation of yellow block crystals. Experimental detailsHydrogen atoms were placed on calculated positions and refined using a riding model. The highest residual electron density peak (0.67 e −3 Å) is located 2.29 Å away from the water oxygen atom; however, refinement of disorder did not lead to a significant improvement of the model.
