Popis: A flexible ditopic ligand 1 containing two N,N,O-tridentate (1,2,3-triazol-4-yl)-picolinamide chelating pockets is reported and the formation of multimetallic architectures is explored in the solid and the solution phase. The self-assembled ZnII complex [Zn4(1)4](ClO4)8 exhibited a folded [2 × 2] square grid supramolecular architecture that selectively assembled in MeCN solution as shown using various spectroscopic techniques. The closely related FeII complex shows equivalent behaviour in the solid state, while a discrete dinuclear species [Cu2(NO3)41]·5MeCN was the sole product observed in the solid state from the reaction between 1 and CuII under similar conditions.
