Abstract
Neutral heteroleptic trithiocyanurato-bridged manganese(i)/rhenium(i)-based M₃LL'-type trinuclear and M₆L₂L″-type hexanuclear metallacages were accomplished in a single step by one-pot synthesis strategy using rudimentary dimetal decacarbonyl (Mn₂(CO)₁₀/Re₂(CO)₁₀), flexible tripodal ligands (L' = 2-ethyl-2((isonicotinoyloxy)methyl)propane-1,3-diyl diisonicotinate (L₁) and 1,3,5-tri(benzimidazol-1-ylmethyl)-2,4,6-triethylbenzene (L₂)) or hexapodal N-donors (L″ = 1,2,3,4,5,6-hexakis(benzimidazol-1-ylmethyl)-benzene (L₃)) alongside of trithiocyanuric acid (L = ttcH₃) as a tris-N,S-chelating bridge via orthogonal bonding approach. The M₃LL' type trinuclear (1-4) and M₆L₂L″-type hexanuclear (5-6) metallacages were characterized by IR, UV/Vis, ¹H NMR spectroscopic and HR-ESI-MS techniques and elemental analysis. Furthermore, the structural elucidation by single-crystal X-ray diffraction techniques revealed a dome-shaped trinuclear metallacage for 1 and an Igloo-type trinuclear cage-like framework for 3 and 4, while the metallacage 6 displayed a hexanuclear hour glass type of architecture.
