Synthesis of a polynuclear complex possessing four spatially arranged rhenium units

• Neutral rhenium(I)-based mixed-ligands tetranuclear complex.
• Four mononuclear complex units are arranged spatially in a molecule.
• Mononuclear complex contains Re(CO)3, pyridinyl and 2-(benzoxazol-2-yl)phenolate.

The reaction of Re2(CO)10 with 2-(benzoxazol-2-yl)phenol (HL) and 1,2,4,5-tetrakis(4-pyridylvinyl)benzene (L2) gives a heteroleptic tetranuclear complex, [((fac-Re(CO)3)L)4(L2)] 1. The corner of 1 comprises four spatially arranged mononuclear units.
