The Newcastle University research output collection, currently available on ePrints, will shortly be moving to a new open repository platform, Figshare. To prepare for the data migration we have paused adding new content to ePrints, and will resume once the new repository is launched. During this time you will continue to have access to ePrints (but no new content will appear). We will share updates here when available.

Abstract

The acid dissociation constants (Ka) of 4-(2′- benzimidazolyl)-3-thiabutanoic acid and related substances were determined by potentiometric titration in 0.1 mol dm-3 (CH3) 4NCl at 25° C. pKa values found were 3.33, 5.46, and 11.32. Stability constants were found for ML2, MHL2, MH3L2, MH4L2, MH-1L 2, MH-2L2 complexes for copper, nickel, and zinc. © 2005 American Chemical Society.
