摘要:
Copper(I) complexes of short-bite aminobis(phosphonite), PhN{P(-OC10H6(mu-S)C10H6O-)}(2) (1) have been synthesized. Reactions of 1 with an excess of CuX (X = Cl, Br, and I) afforded the ligand-bridged binuclear complexes, [PhN(PR-kappa P)(2){Cu(mu-X)(MeCN)}(2)] (2, X Cl; 3, X = Br; 4, X = 1; R = -OC10H6(mu-S)C10H6O-), whereas treatment with 0.5 equiv. of [Cu(MeCN)(4)]PF6 produces the mononuclear bischelated cationic complex, [(PhN(PR-kappa P)(2)}(2)Cu](PF6) (5). Single crystal X-ray structures of complexes 3 and 4 are reported. Complex 3 shows strong pi-pi stacking interactions between the naphthyl moieties, whereas complex 4 shows ligand-supported Cu center dot center dot center dot Cu metallophilic interactions.
