A mixed-valent hexadecanuclear manganese cluster, [MnII2MnIII14(trz)14(thetach)4(μ3-O)8(H2O)10](ClO4)6 (Mn16), containing two MnII and 14 MnIII ions, is constructed from mixed in situ generated ligands, 1,2,3-triazole (Htrz) and 1,3,5-tri(2-hydroxyethyl)-1,3,5-triazacyclohexane (H3thetach). Remarkably, both ligands were not initially added into the reaction system, and their formations involve the in situ ligand decomposition and subsequent condensation reactions. The core of Mn16 is an elongated torus comprised of eight Mn atoms and four [Mn2O2] subunits bridged by oxo or alkoxide. The high-resolution electrospray ionization mass spectrometry (HR-ESI-MS) of Mn16 dissolved in CH3CN indicates its structure remains intact as +3 and +4 species. Temperature and field dependent magnetization revealed predominantly antiferromagnetic exchange interactions within the cluster. The work provides 1-pot synthesis of high-nuclearity manganese clusters using the ligands generated by in situ reactions in a tandem fashion. A new strategy was uncovered consisting of a tandem in situ formation of two ligands which subsequently construct a hexadecanuclear mixed-valent manganese sym. torus. The results came from multiple reactions, including the reaction of 1H-1,2,3-Triazole(cas: 288-36-8Formula: C2H3N3)
1H-1,2,3-Triazole(cas: 288-36-8) belongs to triazoles. Triazoles are an important group of nitrogen-containing five-membered heterocyclic scaffolds. Triazoles are core structures of several drugs and pharmaceutical agents. Triazole derivatives possess antimicrobial, antiparasitic, antidiabetic, analgesic, and anti-inflammatory properties Formula: C2H3N3
