The complexes [Na(CTV) 2 (OH)(H 2 O)](H 2 O)(DMF) 2 ( o ‐carborane) ( 3; CTV=cyclotriveratrylene), [K(OH)(CTV)(DMF)] 2 ( o ‐carborane) ( 4 ), [(DMF)(CTV)] 2 (H 2 O) 4 ( o ‐carborane) ( 5 ), and ( o ‐carborane)(CTV)(DMF) 2 ( 6 ) all form as crystalline inclusion complexes from N , N ′‐dimethylformamide (DMF) solution. Complexes 3 and 4 are the first reported examples of CTV acting as a chelating ligand, with two CTV molecules coordinating cis to the six‐coordinate M + centers (M=Na, K). The extended structures of complexes 3 – 5 are similar, forming extended coordinate and/or hydrogen‐bonding interactions and all feature intracavity complexation of DMF by CTV, while the complex 6 forms an assembly of ( o ‐carborane) ∩ (CTV) ball‐and‐socket supermolecules with DMF as a channel‐type included guest.
