Spectral characterisation of five volatile bis(N-R-salicylaldimine)nickel(II) (where n-R=methyl to pentyl) complexes and single crystal study on methyl analogue

Synthesis, Characterization and Antimicrobial Activities of Co (III) and Fe (III) Complexes of Imino-N-heterocyclic Carbenes Ligands

“…For instance, the imine N=C absorption band seen around 1626cm-1 in 1a was later observed at 1607 cm in the ligand precursors 1a and 1b has been shifted to 1278 cm -1 and 1308 cm -1 in the metal complexes 2 and 3 respectively. These shifts were due to higher Ph-O bond order as a result of the loss of hydrogen from the Ph-OH donor arm [19]. Furthermore, the low-resolution mass spectrometry analysis of the complexes further confirmed the formation of compounds 2 and 3.…”

New solid form of Norfloxacin: Structural studies

“…In the recent years the mass spectrometry was a powerfully method on the study of crystal systems [2,9,10] or on the pharmaceuticals purity [7] as well as on pharmaceuticals actions [6]. We studied the sample of Norfloxacin in vapor phase by using a mass spectrometer with a direct introduction system.…”

Synthesis, crystal structure, thermal stability and biological study of bis{(2-methoxy-6-[(E)-(propylimino)methyl]phenolato}nickel(II) complex

“…Schiff base complexes of nickel with varying structural features exhibit variety of applications in various fields such as catalytic, biological and nanomaterials preparation. The modular synthesis of Schiff base complexes of various metals allows one to control the nature of donor atoms (N, O) [ 1 ] in the coordination sphere, denticity, chelating ability, steric and thermal properties [ 2 ]. Schiff bases complexes are among the most widely studied compounds for over several decades as they show a wide range of applications such as in food industry [ 3 ], as dye [ 4 , 5 ], polymer stabilizers [ 6 , 7 ], intermediates in organic synthesis [ 8 , 9 ], catalysis [ 10 , 11 ], chemo-sensors [ 12 ] and in pigments [ 10 , 13 ].…”
