To limit the exposure of those who work with py and NH3 vapor, the development of effective techniques to sense atmospheric levels of py and NH3 in order to decrease their concentration when required is important. In the present study, we found that crystals of bis(benzimidazole)NiCl2 (1, bis(benzimidazole) = phenylbis(benzimidazol-2-yl)methane)) adsorb py and NH3 vapor with a concomitant color change from purple to green (py) or light purple (NH3). Powder X-ray diffraction, UV–Vis diffuse reflectance, and IR spectroscopic studies revealed that these color changes are induced by the formation of trans-[NiCl2(py)4] (2) or [Ni(NH3)6]Cl2 (3). A time-dependent analysis of the py-vapor adsorption indicated that the formation of 2 from 1 proceeds non-uniformly in the solid. Crystals of 1 were furthermore found to adsorb py or NH3 even at low concentrations (py: ~ 6 ppm; NH3: ~ 33 ppm), albeit that a color change was not observed in these cases.<h3>Graphical abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":803,"journal":{"name":"Transition Metal Chemistry","volume":null,"pages":null},"PeriodicalIF":1.6,"publicationDate":"2024-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140116506","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The reaction between NO and the complex with cyclen is faster than that with the complex with cyclam. However, the reaction of the cyclen complex with NO2− is slower than NO. This research provides detailed reaction kinetics and thermodynamic activation parameters for these interactions for the first time.
