Co3+-Based Building Blocks with Appended Phenol and Catechol Groups: Examples of Placing Hydrogen-Bond Donors and Acceptors in a Single Molecule

This work shows the syntheses, structures, and hydrogen-bonding based self-assembly of Co3+ coordination complexes containing appended phenol and catechol groups. Placement of hydrogen-bond donors (in O–H groups of phenol and catechol) and acceptors (in COamide groups) in a single molecule results in a complementary yet unique self-assembly.
