One end open VnBzn- (n = 1-5; Bz = benzene) and both ends open VnBzn-1- (n = 2-5) vanadium-benzene cluster anions were studied using anion photoelectron spectroscopy and density functional calculations. The smaller (n ≤ 3) VnBzn and VnBzn-1 clusters and corresponding anions were found to have structural isomers, whereas full-sandwiched VnBzn+1 clusters preferred to form multiple-decker sandwich structures. Several isomeric V2Bz2 structures were identified theoretically and the anion photoelectron spectra of V2Bz20/- were explained well by the coexistence of two isomeric structures: (1) a V2-core structure sandwiched between benzene molecules and (2) an alternating sandwich structure with the spin state strongly dependent on the structure. The adiabatic electron affinity of both VnBzn and VnBzn-1 was found to increase with the cluster size at larger sizes (n = 4 or 5) and approaches to that of VnBzn+1. The evolution of the structural and electronic properties of VnBzm and VnBzm- (m = n and n - 1) with size is discussed in comparison with VnBzn+1 and VnBzn+1-.
