Synthesis and Characterization of Homoleptic and Heteroleptic Cobalt, Nickel, Copper, Zinc and Cadmium Compounds with the 2‐(Tosylamino)‐N‐[2‐(tosylamino)benzylidene]aniline Ligand

Abstract

The electrochemical oxidation of anodic metal (cobalt, nickel, copper, zinc and cadmium)

Precursor molecules for 1,2-diamidobenzene containing cobalt(ii), nickel(ii) and zinc(ii) complexes – synthesis and magnetic properties

“…The calculated distances between the two Ni(II) centres and the sulfonyl oxygens lie between 2.096 Å and 2.224 Å. Reported values of this structural motif are in the range of 2.09 44 to 2.43 Å 46 , hence the computations are in line with experimental precedence.…”

“…This is justified by experimental data of a number of structurally characterized Ni(II) complexes where sulfonamido groups act as bidentate donors via N,O coordination. [44][45][46] Starting from a sixcoordinate geometry in which the sulfonyl oxygen atoms act as axial donors, an optimum geometry was found (Table S3 ‡). Consequently, the geometry around the Ni(II) centre is a slightly distorted octahedron.…”

Stacking interactions of resonance-assisted hydrogen-bridged rings and C6-aromatic rings

“…The stacking interactions are mainly connected with aromatic molecules, [1][2][3][4][5][6][7][8][9][10] however it was shown that various rings can form stacking interactions; aliphatic saturated [11][12][13][14][15][16] and unsaturated molecules, 17,18 metal-chelate rings, [19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35][36][37][38] and hydrogen-bridged rings. [39][40][41][42] 2D materials can also form stacking interactions.…”

High-Throughput Small-Molecule Crystallography at the ‘Belok’ Beamline of the Kurchatov Synchrotron Radiation Source: Transition Metal Complexes with Azomethine Ligands as a Case Study

“…Stretching vibrations of the imino group in 2-N-tosylaminobenzaldehyde azomethines are typically observed at 1600-1630 cm −1 and they do not shift significantly upon complex formation [16,[61][62][63]. The spectral changes observed are consistent with the deprotonation and direct involvement of the tosylamino group into the metal binding.…”
