Two novel thioindate-thioantimonate compounds [Ni(dien)(2)](2)In(2)Sb(4)S(11) (1) and [Ni(dien)(2)](3)(In(3)Sb(2)S(9))(2)·2H(2)O (2) (dien = diethylenetriamine) have been solvothermally synthesized and structurally characterized. 1 contains heterometallic pseudosemicube [In(2)SbS(8)] clusters and bow-like trimeric [Sb(3)S(7)] units, which are linked to form a [In(2)Sb(4)S(11)(4-)](n) chain, whereas 2 consists of chain-like [In(6)S(18)] units and pyramidal SbS(3), which are interconnected to give a [In(3)Sb(2)S(9)(6-)](n) layer with a large rectangle-like 12-ring. The optical properties of 1 and 2 have been investigated by UV-vis spectroscopy.
