Structural dimension modulation in a new oxysulfide system of Ae2Sb2O2S3 (Ae = Ca and Ba)

Two oxysulfides Ae 2 Sb 2 O 2 S 3 (Ae = Ca, Ba) with different structural dimensions were successfully discovered. Ca 2 Sb 2 O 2 S 3 contains one-dimensional [Sb 2 O 2 S 3 ] 4− chains, while Ba 2 Sb 2 O 2 S 3 features zero-dimensional [Sb 2 O 2 S 3 ] 4− clusters.
