Crystal structure of cis-[PdCl2(CNMes)2]

Abstract

The interaction between PdCl₂(CH₃CN)₂ and 2,4,6-Me₃C₆H₂NC (MesNC) proceeds with the substitution of acetonitrile ligands and leads to the synthesis of a cis-[PdCl₂(MesNC)₂] complex. The structure of this compound is determined by single crystal X-ray diffraction (XRD). The complex has a slightly distorted square-planar structure of the metal center with two cis-positioned isocyanide ligands. In both CN isocyanide moieties the triple bonds have lengths similar to the lengths of the respective bonds in other isocyanide complexes. In the structure, the cis-[PdCl₂(MesNC)₂] complexes are bound by weak С–H∙∙∙Cl hydrogen bonds and π-stacking interactions.
