Both unit cells contain discrete anions and, basically isostructural, complex cations. The co-ordination sphere of the metal(I) centre is dominated by four imine N atoms [Ag, 2.329(3); Cu, 2.014(14)–2

A colorimetric heterocyclic imine based chemosensor is designed for detection of PO43- and CO32- under physiological pH conditions. The charge-transfer (CT) sensor is highly coloured with PO43- and CO32- recognition giving rise to a purple-to-yellow colour change that is visible to the naked eye and is reversible upon removal of anion.

The compliance of three acyclic flexible ligands of the type N2X2 with -CH2-CH2- linker in the backbone: diiminodi(furan) L1, diiminodi(thiophene) L2 and diiminodiphosphine L3 have been employed for the coordination of chlorogermyliumylidene and gold(I) chloride units. The chlorogermyliumylidenes have been stabilized by the two imino nitrogen coordinating sites present in L1 and L2 yielding compounds 1 and 2 respectively. Based on metal:ligand stoichiometry used, the phosphino groups present in L3 can coordinate to either one AuCl unit giving compound 3 or to two AuCl units forming compound 4. All the compounds have been characterized by NMR techniques and single crystal X-ray crystallography.
Novel Co(II), Ni(II) and Cu(II) complexes involving a 2-thienyl and trifluoromethyl containing symmetrically-substituted tetradentate Schiff-base ligand: Syntheses, structures, electrochemical and computational studies
Abstract Here, we report three novel metal(II) complexes (M = Co, 3a; Ni, 3b; Cu, 3c) involving a symmetrically-substituted N2O2-tetradentate Schiff base ligand bearing trifluoromethyl and 2-thienyl substituents. Complexes 3a–c were readily synthesized upon reaction of the diprotic Schiff base proligand with the appropriate hydrated metal(II) acetates, and isolated as neutral, air and thermally stable
