Spectroscopic, Magnetic, and Electrochemical Studies of a Dimeric N-Substituted-Sulfanilamide Copper(II) Complex. X-ray and Molecular Structure of the Cu2(sulfathiazolato)4 Complex

“…The Cu 2 (stz) 4 complex is a dimer one, classified in the type IV of copper dimers with triatomic NCN bridging groups. An interesting aspect of the ligand in this compound is the presence of a nonlinear bridging NCN, also found in molecules of biological importance like adenine, − and that provides an efficient pathway for coupling magnetism. Considerable attention has focused on the bridging capabilities of a closely related system containing the NCN group such as the copper complexes of the adenine.…”

Spectroscopic, magnetic, and electrochemical studies of a dimeric N-substituted-sulfanilamide copper(II) complex. X-ray and molecular structure of the Cu2(N-(pyridin-2-yl)biphenyl-4-sulfonamidate)4 complex

“…Other non linear triatomic bridging ligands are of NNN or NCN type. The former is observed in case of the 1,3-diphenyltriazene anion [1][2][3][4] and the latter is reported in adenine complexes [5][6][7][8][9][10][11][12]. The structure of this type of complexes is a paddle-wheel similar to that of Cu-acetate and related carboxylates [13][14][15][16][17][18][19].…”
