Heterometallic Pd-II-Ni-II Complexes with meso-Substituted Dibenzotetraaza[14]annulene: Double C-H Bond Activation and Formation of a Rectangular Tetradibenzotetraaza[14]annulene
Three isomeric 2[(PdNiII)-Ni-II] metal complexes, derived from indoleninyl meso-substituted dibenzotetraaza[14]annulene, were synthesized. The resulting dimers feature Ni...Ni or, alternatively, Ni...p interactions in staggered or slipped cofacial structures. A remarkable insertion of palladium into two different CH bonds yielded a 4[(PdNiII)-Ni-II] rectangular complex with dimensions of 8.73 x 10.38 angstrom.
