摘要:
Metal-directed self-assembly approaches led to the formation of two novel boat-shaped palladium(II)-based metallacalixarenes 1 (1 a, 1 b and 1 c) and 2 (2 a, 2 b and 2 c), by using the two new ligands 2,6-bis(1H-naphtho[2,3]imidazol-1-yl)pyridine (L-1) and 1,3-bis(1H-naphtho[2,3]imidazol-1-yl)benzene (L-2) with cis-coordinated Pd-II precursor (tmeda)Pd(ONO2)(2) (tmeda=N, N, N ', N '-tetra-methylethylenediamine), repectively. All complexes with different counterions were systematically characterized in solution, and their structures were determined by X-ray single crystallography analyses in the solid state. The crystal architectures were subtly regulated among different anions through two types (inter- and intra-)molecular C-H hydrogen bonding interactions and other weak interactions. The anion complexation with the two metal-assembled anion receptors were further investigated in solution.
