Hard and soft-donors decorated rhenium based metallocavitands

• Flexible ligands containing two terminal mercaptobenzimidazolyl units.
• Self-assembly of neutral dinuclear metallocavitands.
• Unsymmetrical calix[4]arene-shaped molecules.

Flexible ligands containing two terminal mercaptobenzimidazolyl units were designed, synthesized, and utilized for metallocavitands in the presence of tetrahydroxybenzoquinone and Re2(CO)10. These metallocavitands adopt unsymmetrical calix[4]arene-shaped frameworks, which contain two hydroxyl groups and two thioether units.
