dc.description.abstractIn this contribution, a novel binuclear heteroleptic complex [Pb2L2(CO3)]2CH(3)CN2MeOH (12CH(3)CN2MeOH) is reported, which was fabricated by electrochemical oxidation of a lead anode under an ambient atmosphere in a CH3CN : MeOH solution of N '-isonicotinoylpyrazine-2-carbohydrazonamide (HL). The CO32- anion was produced from the conversion of aerial CO2 by the Pb2+-L complex system under electrochemical conditions. In the structure of 1, ligand L exhibits a tridentate pincer-like N,N ',O-coordination mode, while the CO32- anion exhibits a tetradentate bridging coordination mode with one of the oxygen atoms exhibiting a bridging mu-coordination mode. The metal cations in the structure of 1 are in a five-membered N2O3 coordination environment, formed by covalent bonds. The molecular structure of 12CH(3)CN2MeOH is stabilized by a pair of intermolecular Pb & ctdot;N tetrel bonds formed with one of the NH2 nitrogen atoms of an adjacent complex molecule and with the acetonitrile nitrogen atom, and one Pb & ctdot;O tetrel bond formed with the carbonyl oxygen atom of the other adjacent complex molecule, yielding a 2D supramolecular sheet. This sheet is further stabilized by intermolecular N-H & ctdot;N-acetonitrile and N-H & ctdot;O-carbonate hydrogen bonds and pi(Pyrazine)& ctdot;pi(Pyridine) interactions. The optical properties of the complex were revealed by UV-vis spectroscopy and spectrofluorimetry in MeOH. It was established that the described complex is emissive upon excitation at 340 nm with a broad band from about 500 nm to 780 nm with a maximum at similar to 580 nm, accompanied by a shoulder at similar to 620 nm. The CIE-1931 chromaticity coordinates of (0.28, 0.36) fall within the white gamut of the chromaticity diagram. Thus, complex 1 is a single-component white light-emitting phosphor.
