Abstract

The B3LYP functional and CASPT2 method are utilized to investigate the geometrical and electronic structures of MnS3−/0 clusters. The results show that the stability of the anionic isomers decreases from η2-(S2)MnS− to MnS3− and to η2-(S3)Mn−. The stability of the neutral isomers decreases from η2-(S2)MnS to η2-(S3)Mn and to MnS3. The ground state of the anionic cluster is calculated to be the 5B2 of η2-(S2)MnS− isomer, while that of the neutral is the 4B1 of the same isomer. The photoelectron spectrum of MnS3− is interpreted by electron detachments from the most stable η2-(S2)MnS− isomer and from the metastable MnS3− and η2-(S3)Mn− isomers.
