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)[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) with three Ni(bpy)(3) cations. The compound Ni(bpy)(3)[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)[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). 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) cations.
通过溶剂热技术制备了硫属金属酸盐（T3 团簇化合物）与 Ni-bpy（bpy=2,2'-联吡啶）配合物的超四面体化合物。化合物 Ni(bpy)(3)[H(4)In(10)S(20)]·bpy·2EG·6H(2)O（Mb-InS-1）（EG=乙二醇）由离散的[T(4)In(10)S(20)]（6-）T3 簇组成，其中包含三个Ni(bpy)(3)阳离子。化合物 Ni(bpy)(3)[H(2)In(10)S(19)]·bpy·2HEA·2H(2)O（Mb-InS-2）（EA=乙醇胺）是一维聚合物，其中锯齿形 T3 簇链通过金属-bpy 配合物阳离子平衡电荷。化合物 Ni(bpy)(3)[H(4)In(40)S(74)]·7Hbpy·3HEA·8H(2)O（Mb-InS-3）是具有阳离子层的二维 T3 聚合物Ni(bpy)(3)。将 M-bpy 配合物阳离子整合到硫属化物结构中是为了提高材料的光吸收。电子光谱显示出新的阳离子-阴离子电荷转移（CACT）带，这主要是由 InS T3 超四面体簇和Ni(bpy)(3)阳离子之间的 S···H-C(py)接触引起的。
