Abstract: Cluster ions of niobium and sulfur were generated in laser plasma reactions on a self-built apparatus. Among all Nb_nS_m~+, the cluster cations with the compositions of n<4, m=n+1; n>3, m=n+2 have special high ion intensities in mass spectrum. The cluster anions of high intensities have four more sulfur atoms compared with the relative cations. By analogousing to [Mo_3S_4]~(4+) clusters, it is proposed that these cluster ions contain non-planar puckered rings with quasi-aromaticity.

Key words: laser plasma reaction, quasi-aromativitv mixed cluster ions of niobium and sulfur
