Syntheses and Structures of a Series of Acyclic Diaminocarbene Palladium(II) Complexes Derived from 3,4-Diaryl-1H-pyrrol-2,5-diimines and Bisisocyanide Palladium(II) Complexes
Reactions of 3,4-diaryl-1H-pyrrol-2,5-diimines with various bisisocyanide palladium(II) complexes were studied. The coupling proceeds with one isocyanide ligand to accomplish the acyclic diaminocarbene complexes. The structure of generated diaminocarbene complexes depends on bulkiness of isocyanide ligand in the bisisocyanide complexes of palladium(II). The imino-group of 3,4-diaryl-1H-pyrrol-2,5-diimine reacts with one isocyanide ligand of cis-[PdCl2(CN–R)2] (R = i-Pr, Cy, t-Bu, Bn), and the nitrogen atom of the pyrrole ring is coordinated to the palladium center as the second isocyanide ligand remains intact. In the case of cis-[PdCl2(CN–R)2] (R = 2-acyloxyphenyl, 2-sulfonyloxyphenyl), on…
Intermolecular hydrogen bonding H···Cl− in the solid palladium(II)-diaminocarbene complexes
Abstract Weak intermolecular non-covalent H···Cl− interactions in the solid chelated palladium(II)-diaminocarbene complex cis-[PdCl(CNXyl){C(NHXyl)=NHC6H2Me2 NH2}]Cl (3; Xyl=2,6-Me2C6H3) were studied by XRD followed by appropriate DFT calculations. The N–H···Cl contacts for both NH groups in the carbene moiety are different (N1–H···Cl2 3.5258(19), N2–H···Cl2 3.0797(17) Å). The DFT calculations and topological analysis of the electron density distribution within the formalism of Bader’s theory (QTAIM method) were performed for a model cluster of the carbene complex 3. The theoretical data confirmed that the strength of intermolecular HB H···Cl− is different for two NH-protons of the carbene …
