Indium−Sulfur Supertetrahedral Clusters Integrated with a Metal Complex of 1,10-Phenanthroline

Abstract

A new type of indium-sulfur supertetrahedral compound with unique optical absorption property has been synthesized and characterized crystallographically, in which discrete or polymeric InS-T3 clusters are integrated with metal complex cations of 1,10-phenanthroline.

Non‐Corner‐Capped Discrete T4 Cluster Stabilized by a Metal‐Bipyridine Complex

“…The side length about 15.6 Å (1.6 nm) of the tetrahedron is estimated from the distance of two corner sulfur atoms, the radii of the atoms were not taken into account. The cluster size is larger than that of the earlier reported discrete non‐corner‐capped T3 clusters [In 10 S 20 ] 10– with [Ni(bpy) 3 ] 2+ cations 18,20. The dark red colored crystals of Mb‐InS‐ 4 are illustrated in Figure 3(a).…”

“…The corner Ga III atoms of the T4 clusters are replaced by Sn IV atoms, which is important for the contribution of the stability of the anion by reducing the negative charge. We have prepared a family of discrete non‐corner‐capped T3 clusters [In 10 S 20 ] 10– with [Ni(phen/bpy) 3 ] 2+ cations 18–20. The stability of these isolated T n clusters is ascribed to the steric hindrance and aromatic surrounding of the cations.…”

Synthesis of dihalogenidoindium(III) ions by halide transfer involving tellurium compounds in the presence of hard and soft ligands

“…0.07 g (0.2 mmol) of indium(III) bromide and 0.07 g (0.1 mmol) of [Te(etu) 4 Br 2 ] were dissolved in 6 mL of methanol. The mixture was stirred under argon for 4 h. After this period, the solution was kept undisturbed to give rise to crystals of compound 7.…”
