N2 - The complexes [Na(CTV)2-(OH)(H2O)](H2O)(DMF) 2(o-carborane) (3; CTV = cyclotriveratrylene), [K(OH)-(CTV)(DMF)]2(o-carborane) (4), [(DMF)-(CTV)]2(H2O)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.
