title: Coordination of oxovanadium(V) in an expanded porphyrin macrocyclet.
abstract: The formation of a dioxovanadium(V) complex of an expanded porphyrin-type Schiff base macrocycle is reported; the tetrapyrrolic ligand undergoes a tautomeric shift which permits a bimodal recognition of the nonspherical cationic guest.
