Solid state synthesis and structural characterization of binuclear Cu(I)-SbPh3 complex [Cu(SbPh3)(2)I](2)

Dimeric complex [Cu(SbPh3)(2)I](2) has been synthesized by a solid state re action at a low heating temperature and its crystal structure has been anal yzed by Xray crystallography. The crystal is monoclinic, space group P2(1)/ a (#14), a = 20. 436 (5), b = 14. 125 (3), c = 24. 683 (3) Angstrom, beta = 110. 67 (1)degrees, Z = 4, V = 6666 (2) Angstrom(3); C72H60S4I2Cu2, M-r = 1792, D-c = 1. 787 g . cm(-3), mu(MoK alpha) = 31. 88 cm(-1), F(000) = 3440 , R = 0. 038 and R-w = 0. 043 for 5632 observed reflections (I greater than or equal to 3. 0 sigma(I)) and 361 refined parameters. The result reveals the copper and the bridging iodide atoms form an approximately planar rhomb oid array. Effects of the bulkiness of the ligands upon the structures of t he analogous complexes are discussed.
