Synthesis and structural characterization of mono- and dinuclear Ni^IIand Pd^IIcomplexes derived from tetradentate 1,7-bis-(pyridin-2-yl)-2,6-diaza-1,6-heptadiene

Synthesis, characterization and molecular structures of Ni(II) complexes derived from Schiff base pyridylimine ligands

“…The NiL1 (15) Å] is close to those observed in other aqua nickel complexes [17,18,[25][26][27][28][29][30][31], lengths for Ni-N imine and Ni-N pyridyl bonds are in accordance with other structurally similar complexes [15,[17][18][19]32,33].…”

“…The two chloride atoms are mutually cis with bond distances of 2.4371 (5) [17,18,25]. The molecular structure of compound NiL2 is shown in Figure 5.…”

“…Whilst group 10 transition metal complexes based on pyridylimine ligands have been synthetized being important those of nickel [15,[17][18][19] for their potential as models for the mimicking of active centers of metalloenzymes. Thus, in this report we would like to report our findings on the synthesis, characterization and supramolecular studies in the solid state of a series of Ni(II) complexes derived from pyridylimine ligands.…”

Study of a New Hydrazone System with Ion Complexation Capacity Suitable for Selective Detection

“…This is achieved by generating a change in the electronic, conformational, or optical properties of a supramolecular structure, resulting in a chemical response translated into a signal. Colorimetric and fluorometric sensors use changes in optical properties, absorption or emission, as an output signal [1][2][3][4][5][6]. The great development that spectroscopic methods have undergone in the 20th century made it possible to have adequate analytical techniques for the translation of the signal produced in the coordination process and its subsequent interpretation.…”
