Structural and mechanistic information on the reaction of bicarbonate with Cu(II) and Zn(II) complexes of tris(2-aminoethyl)amine. Identification of intermediate and product species

Synthesis, crystal structure, and photoluminescent property of a novel heterobimetallic Zn(II)–Ag(I) cyano-bridged coordination polymer incorporating a pentameric unit [Ag(CN)2Zhang1, Zhang2, Wang3 et al. 2006Inorganic Chemistry Communications18040View full textAdd to dashboardCite

“…The Zn-N distances range from 2.053(3) to 2.230(2) Å . The structural characteristics are very similar to those for other zinc complexes [7].In compound 1, there exist very weak hydrogen bond interaction (donor-acceptor distances bigger than 2.99 Å ) 1 The tris(2-aminoethyl)amine (tren) ligand (0.668 mmol, 0.10 ml) was added to a 15 ml aqueous solution of ZnAc 2 (0.668 mmol) and formed a colorless solution, which was then added dropwise to a 10 ml aqueous solution of K[Ag(CN) 2 ] (1.670 mmol). Crystals suitable for X-ray structural determination were obtained by slow evaporation at room temperature for a few days.…”

“…[26,27] The pH profiles of the titration curves, including the distribution curves of the Zn 2 + species as a function of pH (Figure 3), were analyzed; the calculated results are summarized in Table 4. A marked change is that the pK a1 of [Zn(L 1 )-…”

“…[26,27] The electrode system was calibrated with buf- The titration data were fitted with the PSEQUAD program to calculate the ligand protonation constants K n , the complex formation constant K ML , and the deprotonation constants of the coordinated water molecules in the absence and in the presence of b-CD.…”
