An Organic Hybrid Indium–Telluride Incorporating Binuclear Complexes [In₂(ea)₄]²⁺ with a Bridging Oxygen Donor

Abstract

The new organic hybrid indium−telluride [In 2 (ea) 2 Te 2 ] n (1; Hea = ethanolamine) exhibits a new type of onedimensional polymeric chain based on the linkages of dinuclear [In 2 (ea) 4 ] 2+ and [In 2 Te 4 ] 2− units, which offers the first example of an indium−telluride framework incorporating binuclear complexes [In 2 (ea) 4 ] 2+ with a bridging O donor. 1 shows a distinctive photocurrent response and photocatalytic properties under visible-light illumination.

Two Organic Hybrid Manganese Selenoarsenates: The Discovery of One-Dimensional Low-Valent Selenoarsenate(II)

“…The slightly sharp bands along Y–A–B–D–E–C reveal the presence of N–H···Se H-bond interactions between the complex [Mn­(en) 3 ] 2+ cations and 1D manganese selenoarsenate [MnAs II 2 Se 4 ] 2– anions. A similar phenomenon has also been observed in other chalcogenidometalates Figure c shows the total and partial DOS of 1 .…”

“…A similar phenomenon has also been observed in other chalcogenidometalates. 25 Figure 3c shows the total and partial DOS of 1. The major contributions to the frontier regions (such as VB and CB) come mainly from the 1D [MnAs II 2 Se 4 ] 2− anion, and the small contributions to the frontier regions stem from the [Mn(en) 3 ] 2+ cation, showing that [Mn(en) 3 ] 2+ as a counterion balances the charge of the 1D [MnAs II 2 Se 4 ] 2− polymeric anion.…”
