Intermolecular hydrogen bonding (dashed lines) between the carboxylate oxygen atom (O5) of a shi3− ligand and a coordinated methanol molecule (O11) of a neighboring metallacrown that then generates a one-dimensional chain. For clarity only the hydrogen atoms involved in the interactions have been included. [Symmetry codes: (i) −x + 1, −y + 2, −z + 1; (ii) −x + 1, −y + 1, −z + 1; (iii) x, y − 1, z.] |
