Experimental and theoretical investigations of the self-assembly process of a Pd(II) coordination ML square-based pyramid (SP) were conducted. It was found that the probable self-assembly pathway, in which the dimerization of ML with two M leads to SP, expected from the connectivity of the building blocks is not a major self-assembly pathway to the ML SP. Whether the ML SP is assembled or ML is trapped is determined by an inter- or intramolecular reaction in a chain-like MLX, where X is a leaving ligand. The kinetically trapped state where the ML SP is produced from ML beyond the Boltzmann distribution was realized by a concentration-induced process and was kept for at least 2 months at 298 K.
