Abstract
This work describes the facile and one-step crystallization strategy for the preparation of the title complex through simple mixing of the aqueous reactants, and thus eliminates the need for hydrothermal synthesis. The structural study on the harvested crystalline material, confirms the absolute reproducibility of the title complex by this newer method as well. The suitability of our method in achieving the bulk purity of the title compound, is fully ascertained by elemental analysis, and by powder XRD methods. Due to the presence of metal bound water, and extensive hydrogen bonds in the structure, the system is considered to be very suitable for the proton conduction applications. However, despite the popularity of the compound in the field of MOFs, such studies were never performed. The compound's AC impedance experiments proves the proton conducting characteristics of the title complex under 100% RH .The Ea value implies that the Grotthuss process is followed. Proton conductivity vanishes under dry conditions, but is restored upon re-exposing the sample to the humidity. As a result, the current study emphasises the utility of this well-known and non-hazardous framework for a variety of proton electrolyte applications.
