Intermolecular hydrogen bonding between adjacent metallacrowns and between the MC and the lattice DMF molecule. For clarity, only the H atoms (white) involved in the hydrogen bonding have been included and only the atoms involved in the hydrogen bonding have been labelled. See Fig. 1 for display details.
