Two thioindates [M(en)(3)](0.5) InS2 [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 [InQ(2)(-)](n) (Q = S, Te) anions built from InQ(4) tetrahedra. The band gaps of 3.47 eV for 1 and 3.31 eV for 2 have been derived from optical absorption spectra.
