    • 2 = 1.080. Thirteen water molecules and a single methanol solvent molecule were located in the crystal lattice. The hydrogen atoms were not located on the water molecules or hydroxide in determining the crystal structure. This molecule also has an interesting network of hydrogen bonds that surround the metallacrown. Hydrogen bonds link the water molecules that are bound to ring metal-encapsulated metal-ring metal. This linkage of hydrogen bonding is found on both faces of the metallacrown. Three of the L-alaha ligands in the metallacrown have a hydrogen bond from a water molecule to the amine nitrogen.

    • 4 are shown in Supporting Information. Two proton resonances are predicted for glycine hydroxamic acid for the two inequivalent α protons. However, we observe only one broad peak.

    • note
    • 1g transitions, with no observable intensity for the latter in the ligand field region. There are also significant changes in the CD intensities which are not observed in the UV-vis spectra.
