Abstract

A compact supersonic source is used in conjunction with a Fourier transform ion cyclotron resonance (FT-ICR) mass spectrometer to generate and study the gas-phase reactivities of V14C12,13+ and V14C13+. Sequential reactions with up to 8 H2O molecules result in the formation of V14C12,13(OH)2(H2O)6+ and V14Co(OH)4(H2O)4+ by loss of H2 or attachment of H2O. Both ions are observed to attach up to 8 CH3CN molecules. In light of an earlier study which indicated that Nb4C4+ has a slightly distorted 2 × 2 × 2 cubic structure, these results provide evidence for the proposed 3 × 3 × 3 cubic structure of V14C13+ where the 8 metals in the corners are the active binding sites. The similarity of the reactivity of V14C12+ suggests an analogous structure.
