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⁺ and V₁₄C₁₃⁺. Sequential reactions with up to 8 H₂O molecules result in the formation of V₁₄C_12,13(OH)₂(H₂O)₆⁺ and V₁₄C₁₃(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.
