Synthesis and characterization of binuclear palladium(I) compounds and the influence of competing arenes
摘要:
The binuclear palladium(I) compounds, [Pd(2)(Ga(2)Cl(7))(2)(C(7)H(8))(2)] (1), [Pd(2)(GaCl(4))(2)(C(9)H(12))(2)]center dot C(9)H(12) (2) and [Pd(2)(Ga(2)Cl(7))(2)(C(6)H(5)Cl)(2)] (3), have been prepared from palladium(II) chloride in gallium(III) chloride-arene reaction media. All isolated crystalline solids (1, 2 and 3) have been structurally characterized by single crystal X-ray diffraction and Raman spectroscopy. The results form quantum chemical calculations on the interaction energies of the arenes and the dipalladium unit of these compounds is also presented. (C) 2010 Elsevier B.V. All rights reserved.
