Abstract

Single-crystal X-ray structures of dimeric quinoxaline aldehyde (QA), quinoxaline dihydrazone (DHQ) and HQNM (Goswami S et al. 2013 Tetrahedron Lett. 54 , 5075–5077. ( doi:10.1016/j.tetlet.2013.07.051 ); Goswami S et al. 2014 RSC Adv. 4 , 20 922–20 926. ( doi:10.1039/C4RA00594E ); Goswami S et al. 2014 New J. Chem. 38 , 6230–6235. ( doi:10.1039/C4NJ01498G )) are reported along with the theoretical study. Among them, QA is not acting as an active probe, but DHQ and HQNM are serving as selective and sensitive probe for the Fe 3+ cation and the Ni 2+ cation, respectively. DHQ can also detect the Fe 3+ in commercial fruit juices (grape and pomegranate).
