Crystal structure of poly[bis(adipate-κ⁴ O,O′:O′′, O′′′)(1,4-bis(2-methyl-1H-benzo[d]imidazol-1-yl)benzene-κ² N:N′)dizinc(II), C₃₆H₃₈N₄O₈Zn₂

Abstract

C 36 H 38 N4O 8 Zn 2 , monoclinic, P21/n (no. 14), a = 13.144(3) Å,CCDC no.: 1470648 Tables 1 and 2 contain details of the measurement method and a list of the atoms including atomic coordinates and displacement parameters. Source of materialA mixture of Zn(Ac) 2 · H 2 O (43.9 mg, 0.2 mmol), adipic acid (29.2 mg, 0.2 mmol), NaOH (8.0 mg, 0.2 mmol) and 1,4-bis(2-methylbenzimidazol-1-ylmethyl) benzene (36.6 mg, 0.1 mmol) in 10 mL distilled H 2 O was sealed in a 25 mL Te on-lined stainless steel container and heated at 160°C for 4 days. After the mixture was cooled to room temperature at a rate of 5°C/h, colorless block crystals were obtained with a yield of 56% (based on Zn).

“…The Zn(II) ion presents a distorted tetrahedral coordination geometry, ligated by two oxygen atoms (O1A and O5) from two symmetry-related carboxylate groups of 4,4′-sulfonyldibenzoate and two nitrogen atoms [18]. In the title complex, two beb ligands adopt symmetric trans-conformation with the N donor · · · N-C sp 3 · · · C torsion of 30.496°and 28.589° [19], respectively. Each Zn(II) ion links…”
