Heterocyclic compounds can be divided into two categories: alicyclic heterocycles and aromatic heterocycles. Compounds whose heterocycles in the molecular skeleton cannot reflect aromaticity are called alicyclic heterocyclic compounds. Compound: 14694-95-2, is researched, Molecular C54H45ClP3Rh, about An insight into the coordination specificity of polyaromatic hydrocarbons (PAHs) grafted hydrazones towards rhodium(III), the main research direction is rhodium polyaromatic hydrocarbon complex preparation redox potential; frontier mol orbital rhodium polyaromatic hydrocarbon complex; crystal structure rhodium polyaromatic hydrocarbon complex.Application of 14694-95-2.
Upon treatment of the polyaromatic hydrocarbon (PAH) grafted hydrazones HL with [RhCl(PPh3)3], complexes of type [Rh(L)Cl2(PPh3)2] were isolated. The X-ray diffraction technique was used to elucidate the structures of three complexes. The rich spectral features of the complexes in the UV-vis region were explained by TD-DFT and their redox active nature has been validated from the well-defined responses at mild potentials as well as from a theor. investigation of the redox orbitals. Intra-mol. π-π stacking interactions coupled with the electron withdrawing ability of the pendant PAH moiety within the ligand framework play a significant role in altering the mode of coordination (flexidentate behavior of HL) as well as the metal-ligand bond parameters.
