Multicomponent self-assembly of Re2(CO)10, diaryl dichalcogenide ligands (REER), and phenyl-1,3,5-tris(isonicotinate) (ptin) under solvothermal conditions has resulted in the formation chalcogen-bridged trigonal metallaprisms general formula [{(CO)3Re(μ-ER)2Re(CO)3}3(μ3-ptin)2] (1–5), wherein E = S, Se R phenyl, p-tolyl, benzyl. Oxidative addition disulfide/diaryl diselenide to Re2(CO)10 with ester-functionalized tritopic linker ptin yielded 1–5 facile reaction conditions. The have been...

A new series of thiolato-bridged manganese(I)-based supramolecular rectangles have been achieved by three-precursor self-assembly Mn2(CO)10, diaryl disulfides (RSSR), and linear ditopic azine ligands (L) [L = pyrazine (pz), 4,4′-bipyridine (bpy), trans-1,2-bis(4-pyridyl)ethylene (bpe)] using a one-pot synthetic strategy. Oxidative addition RSSR (diphenyl disulfide p-tolyl disulfide) to manganese decacarbonyl in the presence rigid bidentate afforded metallarectangles general formula...
