A 3D nickel(II) coordination polymer constructed by mixed- ligand strategy: synthesis, crystal structure and sensing of Hg(II) ion

Fast industrialization, increasing population, rapid urbanization, and the greediness of creamy layer in the society without the issues of caring the sustainability of ecosystem are the main out of many reasons behind the environmental catastrophe. The ecological balance is disturbed with the noxious materials generated from the uncontrolled use of modern science and technology and also unscientific and unsystematic societal growths. To save the modern civilization, a fast‐track task is the monitoring of the toxic materials for the maintenance of sustainable ecological health and their utilization in a circular economy. Accordingly, optical methods are employed for the detection and estimation of environmental contaminants for immediate monitoring. The stability and structural tunability of the coordination polymeric (CPs) materials make them promising optical sensors for easy, low cost, reliable, selective, and sensitive detection of toxic ions/molecules. The crystallinity, thermal, mechanical, magnetic, and optical stability and flexibility of the CPs play a beneficial role for the accurate and stress‐free recognition of the toxicants. In this review, the recent developments as well as the outlook on the sensing of pollutants at a very low concentration level using CPs as selective and specific sensors by spectro‐fluorometric method are summarized. The progresses and challenges in the fabrication of hybrid materials and understanding their structure property correlations are described with an aim to motivate and facilitate the future researchers to perform research in the area.

This study focuses on the synthesis, characterization, and evaluation of NiBIDP and CuBIDP mixed‐ligand complexes. Synthesized with high yields in ethanol‐based solutions, these complexes demonstrate exceptional stability and non‐hygroscopic properties, with melting points exceeding 300°C. Solubility tests reveal compatibility with organic solvents such as acetonitrile, DMF, and DMSO, while being insoluble in water. Characterization through UV‐visible, IR, and mass spectrometry confirms octahedral coordination geometries around Ni(II) and Cu(II) centers. Thermal stability assessments indicate robust properties up to 180°C for NiBIDP and 170°C for CuBIDP. Computational analyses reveal significant electron localization and enhanced electron‐accepting capabilities in CuBIDP, as evidenced by its low LUMO value and high electrophilicity index. Molecular electrostatic potential (MEP) analyses identify nucleophilic sites important for protein interactions, underscoring their potential in catalysis and materials science. Biological evaluations show that although the BI and DP ligands exhibit moderate antimicrobial, anti‐inflammatory, and antioxidant activity, their metal complexes, particularly CuBIDP, demonstrate enhanced efficacy. Molecular docking studies further highlight the improved binding affinities of NiBIDP and CuBIDP with target proteins, suggesting their potential as therapeutic agents in drug discovery. In conclusion, this study provides significant insights into the structural, electronic, and biological properties of NiBIDP and CuBIDP complexes, supporting their development as versatile compounds in biomedical and materials science applications. Key outcomes include enhanced stability and bioactivity of metal complexes compared with their ligands, as well as promising therapeutic potential revealed through molecular docking analyses.
