The fast development of the design, construction and application of metal-organic materials including infinite metal-organic frameworks (MOFs) and discrete metal-organic cages (MOCs) has not only propelled the advance of modern supramolecular syntheses to an unprecedented level, but also burgeoned various kinds of detection and characterization technologies. Herein, complementary techniques, including diversified NMR and ESI-MS solution spectrometry, solid state crystallography and theoretical simulation are exploited to elucidate the structural evolution of a dynamic supramolecular coordination system involving Pd(II)-MOCs of different compositions. The profit from the combination of various kinds of modern techniques verifies the anion template effect which leads to preferred formation and further conversion of Pd2L4 or Pd3L6 cages based on certain anions' overwhelming signals.
