Reactivity of [PdCl(μ-med)]2 with monodentate anionic ligands. Structure of dinuclear complexes [Pd(X)(μ-med)]2 (X=SCN−, ). [Hmed=N-2-mercaptoethyl)-3,5-dimethylpyrazole]
摘要:
The reaction of the complex [PdCl(mu-med)](2) (Hmed = N-(2-mercaptoethyl)-3,5-dimethylpyrazole) with NaCN, NaSCN or NaN3 in presence of AgBF4, yielded complexes with formula [Pd(X)(mu-med)](2) (X = CN (1), SCN (2) or N-3-(3)). These complexes have been characterised by elemental analyses, conductivity measurements, IR and NMR spectroscopies. X-ray crystal structures of [Pd(SCN)(mu-med)](2) center dot 0.5CH(3)CN and [Pd(N-3)(mu-med)](2), are presented. These complexes consist of thiolate-bridged dinuclear units. Each Pd(II) is coordinated by a pyrazole nitrogen, two bridging sulfur atoms and one SCN (2) or N-3-(3) anion. (C) 2008 Elsevier B. V. All rights reserved.
