Abstract:
Herein, we have synthesized a Co(II)-based 2D coordination polymer [Co(5-AIA)(Imidazole)] (CP1) (AIA = 5-aminoisophthalic acid) via a solvothermal approach. SCXRD (single-crystal X-ray diffraction) was utilized to analyze the crystal structure of fabricated CP1. Moreover, PXRD, TGA, FTIR, and SEM analyses were done to identify the structural features of fabricated CP1. The standard rod depiction of CP1 exhibits underlying net topology, and the hydrogen-bonded network depicts underlying net topology. The fluorescence detection of inorganic anions using CP1 showed a promising result of 90.3% for MnO4 -. The electrochemical analysis of CP1 was done under a basic medium utilizing a 3 M KOH electrolyte through CV (cyclic voltammetry) and GCD (galvanic charge-discharge) techniques which show a 134.75 F g-1 specific capacity at a current density of 1 A g-1. Furthermore, CP1 shows a 94% retention capacity after 2500 cycles at a 20 A g-1 current density.

02:34Structural Isomerism
Isomers are different chemical species that have the same chemical formula. Structural isomerism of coordination compounds can be divided into two subcategories, the linkage isomers and coordination-sphere isomers.
Linkage isomers occur when the coordination compound contains a ligand that can bind to the transition metal center through two different atoms. For example, the CN− ligand can bind through the carbon atom or through the nitrogen atom. Similarly, SCN− can...

In these complexes, transition metals form coordinate covalent bonds, a kind of Lewis acid-base interaction in which both of the electrons in the bond are contributed by a donor (Lewis base) to an electron acceptor (Lewis acid). The Lewis acid in...

03:02Colors and Magnetism
When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human...
