WebIn this work, we isolated a pentadentate [P2N2S] phosphine-thiocarbohydrazone ligand H2L with a bulky phosphine group in both linker domains that undergoes an oxidation process in solution. This ligand was synthesized by a direct reaction between two equivalents of 2-diphe-nylphosphinebenzaldehyde and one equivalent of thiocarbohydrazide. Two types of … WebMar 17, 2024 · In addition, a red phosphorescence, which may be assigned to the triplet state localized in the phosphine-M3Cl2 (M = Cu, Ag), is observed for the trinuclear complexes at low temperature. Neither the second-long phosphorescence nor the red emission, are observed for coumarin ligand and thus, are a result of the coordination to …

Phosphine (IUPAC name: phosphane) is a colorless, flammable, highly toxic compound with the chemical formula PH3, classed as a pnictogen hydride. Pure phosphine is odorless, but technical grade samples have a highly unpleasant odor like rotting fish, due to the presence of substituted phosphine and … See more Philippe Gengembre (1764–1838), a student of Lavoisier, first obtained phosphine in 1783 by heating white phosphorus in an aqueous solution of potash (potassium carbonate). Perhaps because of … See more PH3 is a trigonal pyramidal molecule with C3v molecular symmetry.
