title: Indium sulfide clusters integrated with 2,2'-bipyridine complexes.
abstract: Supertetrahedral compounds of chalcogenometalates (T3 cluster compounds) integrated with Ni-bpy (bpy = 2,2'-bipyridine) complex were prepared by a solvothermal technique. The compound [Ni(bpy)(3)](3)[H(4)In(10)S(20)]·bpy·2EG·6H(2)O (Mb-InS-1) (EG = ethylene glycol) consists of discrete T3 clusters of [H(4)In(10)S(20)](6-) with three [Ni(bpy)(3)](2+) cations. The compound [Ni(bpy)(3)](2)[H(2)In(10)S(19)]·bpy·2HEA·2H(2)O (Mb-InS-2) (EA = ethanolamine) is a 1-D polymer, in which zigzag T3 cluster chains are charge balanced by metal-bpy complex cations. The compound [Ni(bpy)(3)](7)[H(4)In(40)S(74)]·7Hbpy·3HEA·8H(2)O (Mb-InS-3) is a 2-D T3 polymer with cation layers of [Ni(bpy)(3)](2+). Integrating M-bpy complex cations into chalcogenido structures has been made with the aim of improving the photoabsorption of the materials. The electronic spectra showed the new bands of cation-anion charge-transfer (CACT) that is mainly caused by the S···H-C(py) contacts between the InS T3 supertetrahedral clusters and the [Ni(bpy)(3)](2+) cations.
