Solid State Synthesis and Structural Characterizationof Binuclear Cu( I)-Sb Ph_3 Co m plex 〔 Cu( Sb Ph_3)_2 I〕

Dimeric complex 〔Cu(SbPh 3) 2I〕 2 has been synthesized by a solid state reaction at a low heating temperature and its crystal structure has been analyzed by X ray crystallography. The crystal is monoclinic, space group P2 1/a (#14), a = 20 436(5), b=14.125(3), c=24.683(3) , β=110.67(1)°, Z=4, V =6666(2) 3; C 72 H 60 Sb 4I 2Cu 2, M r = 1792, D c = 1.787 g·cm -3 , μ (Mo Kα ) = 31.88 cm -1 , F(000)=3440, R= 0.038 and R w= 0.043 for 5632 observed reflections ( I≥3.0σ(I) ) and 361 refined parameters. The result reveals the copper and the bridging iodide atoms form an approximately planar rhomboid array. Effects of the bulkiness of the ligands upon the structures of the analogous complexes are discussed.\;
