A series of one-dimensional (1-D) telluridoindate compounds built from InTe4 tetrahedra sharing opposite edges were synthesized, and the structures of the {[InTe2-]}∞ chains were classified as three types. Compound [Zn(taa)(μ-tren)0.5][InTe2]Cl (Ia) has a common structure feature of a 1-D straight chain (type I). Compounds [M(en)3]In2Te4·en (M = Ni (IIa) and Co (IIb)) have a sinusoidal 1-D structure with [In4Te8] 4- periodic units (type II), while compounds [M(en)3]2(en)0.5In4Te8 (M = Mn (IIIa), Fe (IIIb), and Zn (IIIc)) show another type of sinusoidal anionic chain (type III). The repeating unit of type III consists of eight edge-sharing tetrahedra for a complete sinusoidal period, [In8Te168-]n. Although numerous 1-D polymeric anion chains built from MQ4 tetrahedra with the formula of {[MQ2]n-}∞ exist, these chains are usually straight. The compounds of types II and III are rare examples of 1-D chains within main group chalcogenometalates.
