AI Article Synopsis
- A hydrothermal reaction involving CuI, KI, and TMBP has led to the creation of a water-stable 2D coordination polymer called Cu(TMBP)I3 (1) that incorporates the triiodide anion I3(-).
- Unlike other metal triiodide complexes, this polymer shows minimal distortions in the bond distances of the I3(-) units, which helps form continuous chains of copper(I) centers.
- The findings from the study indicate that the I3(-) ion plays a key role in linking the copper(I) centers, as reflected by its electronic properties, including band gaps and electrical conductivity.
Article Abstract
From a hydrothermal reaction using CuI, KI, and 3,3'5,5'-tetramethyl-4,4'-bipyrazole (TMBP), the triiodide anion I3(-) has been integrated into the water-stable 2D coordination polymer Cu(TMBP)I3 (1). In contrast with other metal triiodide complexes, 1 features remarkably small distortions in the bond distances associated with the I3(-) units (i.e., the Cu-I and I-I bonds), which effectively link up the copper(I) centers into infinite CuI3 chains. The electronic band gaps and electrical conductivity data are also found to be consistent with the I3(-) ion acting as an effective linker across the copper(I) centers.
