A TpyRu²⁺-based bismetallopolymer and its performance in catalytic water oxidation (Tpy = 4-(p-methoxyphenyl)-2,2′:6′,2′′-terpyridine)

Abstract

A bismetallo-organic polymer was successfully prepared by treating a metallo-ligand with Ag(+); characterization was accomplished by NMR, UV-vis, and single crystal X-ray analyses. This heteronuclear polymer achieved more than a two-fold turnover number (TON) and a faster reaction rate in comparison to a Ce-driven Ru-monomer in catalytic water oxidation.

Ruthenium–Benzothiadiazole Building Block Derived Dynamic Heterometallic Ru–Ag Coordination Polymer and Its Enhanced Water-Splitting Feature

“…The coordination of each Ag ion with the two nitrogen atoms of two thiadiazole groups and one oxygen of the ClO 4 moiety introduced a rather unprecedented distoted-trigonal-planar geometry for 3 with the corresponding bond angles N2–Ag1–O5, N4–Ag1–O5, N2–Ag1–N4 of 124.95(7), 86.8(6), and 147.05(17)°, respectively (Figure S4b in the Supporting Information) . The distances between Ru–Ag and the closest two Ru centers in 3 (Figure ) were 6.535 and 11.298 Å, respectively.…”
