Abstract The preparation, crystal structures and optical absorption spectra of [H3N(CH2)6NH3]BiX5 (X= I, Cl) and [H3N(CH2)6NH3]SbX5 (X =I, Br) are reported. The anions of the compounds consist of MX6-octahedra (M =Bi, Sb) sharing cisvertices in one-dimensional zig-zag chains. Because of their one-dimensional character, a blue shift of the excitonic absorption bands, in com parison to those of higher dim ensionality systems (MX3), is observed.

Two thioindates [M(en)3]0.5InS2 [en = ethylenediamine; M = Ni (1), Co (2)] were prepared by the reaction of In2S3, Ni (or Co) and S under solvothermal conditions, and their crystal structures have been determined. Both compounds are isostructural and crystallize in the orthorhombic space group Cmcm. The crystal structures consist of a new type of 1-D sinusoidal chain, which complements the reported I - III types of 1-D [InQ2−]n (Q = S, Te) anions built from InQ4 tetrahedra. The band gaps of 3.47 eV for I and 3.31 eV for 2 have been derived from optical absorption spectra.
