In an article, author is Cindric, Marina, once mentioned the application of 1591-31-7, Name is 4-Iodo-1,1′-biphenyl, molecular formula is C12H9I, molecular weight is 280.1, MDL number is MFCD00019028, category is thiomorpholine. Now introduce a scientific discovery about this category, Formula: https://www.ambeed.com/products/1591-31-7.html.
Eight mononuclear [Ni(sal 4-Phtsc)center dot D] thiosemicarbazonato complexes [sal4-Phtsc = salicylaldehyde 4-phenylthiosemicarbazonato ligand; D = imidazole (1), methylimidazole (2), pyridine (3), 4-aminopyridine (4), 4-methylpyridine (6), morpholine (7), thiomorpholine (8), 2-aminophenol (9)] and one dinuclear {[Ni(sal 4-Phtsc)](2)center dot D} center dot 2DMSO [D = 4,4′-bipyridine (5)] complex have been prepared by adding the corresponding Lewis base to the methanol suspension of the parent complex [Ni(sal 4-Phtsc)(H(2)sal4-Phtsc)]center dot CH3OH. The exchange of the neutral salicylaldehyde 4-phenylthiosemicarbazone (H(2)sal4-Phtsc) ligand in the parent complex for the appropriate Lewis base has been confirmed by IR spectroscopy and powder X-ray diffraction (PXRD) in the solid state. The single-crystal X-ray diffraction of seven complexes 1 and 3-8 confirmed the formation of the complexes with the Ni-II ion, coordinated through O,N,S-donor atoms from the dibasic salicylaldehyde 4-phenylthiosemicarbazonato ligand and endocyclic N-donor atom from the neutral ligand D in the form of a distorted square-planar coordination. NMR spectroscopy in DMF or DMSO and quantum mechanical calculations have been performed in order to explain and compare the stability of the complexes in solution, depending on the polarity of solvents in the context of donor properties and the nucleophilicity of the heterocyclic Lewis base. The single-crystal X-ray data enables a comparison with calculated standard Gibbs energies of binding in the context of crystal packing forces, leading to a general conclusion that the stability of the mononuclear complexes results in the formation of more stable hydrogen-bonded cyclic dimers as a crystal packing pattern.
