An octanuclear pyromellitimidato(2-) palladium complex: coordinative assembly of a molecular box

摘要

Reaction of pyromellitimide with the binuclear palladium complex [Pd_2(#mu#-Cl_2)(1,2-C_6H_4NMe_2)_2] in the presence of base affords a box-like, pyromellitimidato(2-), octapalladium complex exhibiting helical chirality, for which ~1H NMR and single crystal X-ray data are reported.
