Still, challenges are well acknowledged for the review consideration of Zn/Cd–OCN complexes with nitrogen and oxygen donor ligands. Accordingly, this review presents a fresh perspective on the synthesis, X-ray crystallographic features, characterization, supramolecular noncovalent interactions (SNCIs), and applications of Zn/Cd–OCN complexes, drawing on available X-ray structures from 2009 to 2025. The article successfully discusses the scope and objectives, as well as the μ-bridging propensity of OCN⁻ co-ligands with Zn/Cd metal ions. Further, the review covers applications in antimicrobial, fluorescence, CO₂ sorption, and DFT-based limited studies, including MEP/ESP, HOMO-LUMO, Hirshfeld surfaces, semiconducting, and band properties. Additionally, this article sheds light on the limited Spodium bonding features. Investigations such as QTAIM/NCI plots, RDG, BCP, AIM, and NBO characterize the presence of a Spodium bond in the complexes. Overall, the article highlights the limited characterization, biological, and DFT-based properties of Zn/Cd–OCN complexes. It discusses the challenges and future outlooks through a critical discussion of refining synthetic strategy and the potential for complex applications in materials science. It explores promising future studies in biological fields that use AI or bioinformatics. This review provides novel research ideas into current trends in the coordination chemistry of Zn/Cd–OCN complexes.

Its negative impacts on construction sectors such as compromising concrete integrity, strength and elastic modulus require urgent attention. This study investigates the strengths, sustainability and durability of concrete produced with low water – cement ratio and Optima 206 Superplasticizer. The study aims at eradicating the issue of sudden collapse of concrete structures emanating from the use of high water - cement ratio, poor mix proportion and poor workability. In the experiment, the two different water – cement (W/C) ratios (0.6 and 0.43) with 1:2:3 concrete mix proportion were used for concrete production. The concrete samples produced were cured in water for 3, 7 and 28 days, respectively. Concurrently, the fresh and hardened properties of concrete were determined in accordance with SANS 10100–2: 2014, SANS5862–1:2006, SANS5863: 2006, and SANS 50196–3 standards while the results of investigations were modeled with multilinear regression analysis. The experimental results showed that concrete with 0.43 W/C surpassed that of 0.6 W/C in compressive, tensile and flexural strengths, modulus of elasticity (MOE), and Variation in MOE by 59.09, 60.94, 61.01, 10.8 and 29.7% respectively with the help of optima 206 superplasticizer. Also, the water absorption (WA) and carbon dioxide emissions from 0.43 W/C – concrete are by 1.36 and 3.60% less than that of 0.6 W/C ratio – concrete, thus, increase the concrete durability and environmental sustainability. Likewise, the optimum compressive, tensile, and flexural strengths, and modulus of elasticity (MOE) of 0.43 - W/C ratio – concrete predicted by regression model are by 29.2%, 80.4%, 45.8% and 9.9% more than that of 0.6 W/C ratio-concrete with coefficient of determination (R²) values range of 0.971–0.976 indicating the strong fixing of the data by the statistical model while its WA reduced to 0.064%. In conclusion, the binary application of low W/C ratio (such as 0.43), Optima 206 superplasticizer and progressive increase in concrete's curing ages are good for the production of sustainable concrete for industrial use. Also, based on experimental and model's predictions, application of 0.43 W/C ratio together with superplasticizer is recommended for the production of sustainable concrete for the construction of high-strength infrastructures such as high-rise buildings, beams, columns, slabs, bridges, culverts and road – pavements. For better improvement, further investigation is required on application of low W/C ratio such as 0.43 W/C ratio on concrete's durability and variation in MOE.</div></div>","PeriodicalId":100233,"journal":{"name":"Chemistry of Inorganic Materials","volume":"8 ","pages":"Article 100145"},"PeriodicalIF":0.0,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146172633","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
