An antiferromagnetically coupled hexanuclear copper(II) Schiff base complex containing phenoxo and dicyanamido bridges: Structural aspects and magnetic properties

Synthesis, structural characterization and thermal properties of a new copper(II) one-dimensional coordination polymer based on bridgingN,N′-bis(2-hydroxybenzylidene)-2,2-dimethylpropane-1,3-diamine and dicyanamide ligands

“…The design and synthesis of polymeric coordination compounds of 3d transition metals have attracted much interest in the search for functional materials with wide-ranging applications such as model compounds for the investigation of the role of polymetallic active sites in biological systems and new magnetic molecular materials (Sadhukhan et al, 2011;Bhar et al, 2011;Talukder et al, 2011). Complexes derived from N,N 0bis(2-hydroxyphenyl)propane-1,3-diamine (H 2 L) and its derivatives have been used widely in the construction of di-or trinuclear complexes due to their facile preparation and varied chemical properties (Carbonaro et al, 1999;Heinicke et al, 2005;Drew et al, 1985).…”

On the other hand, the coordination chemistry of the copper(II) ion is of considerable interest currently, particularly due to potential applications in the areas of molecular biology and magnetochemistry (Talukder et al, 2011;Li et al, 2014;Hopa et al, 2015). Bridging ligands such as N 3 À , NCS À , NCO À and N(CN) 2 À play a key role in the preparation of polynuclear coordination compounds.…”

Synthesis, characterization, and structures of two new tetranuclear copper complexes with azido/dicyanamide bridges containing chiral Schiff base ligand

“…While the appearance of three sharp and strong stretching frequencies in the 2310-2160 cm -1 region confirms the presence of dicyana mide anions in complex II. The peaks at 2306, 2239 and 2168 cm -1 are characteristic for expected absorp tion of asymmetric and symmetric vibrations of the ν(C≡N) groups [18,19].…”

A novel trinuclear copper(II) complex containing a symmetric tetradentate N2O2 Schiff base ligand: Synthesis, characterization, crystal structure and its usage as a new precursor for the preparation of CuO particles

“…Multinuclear copper(II) complexes containing Schiff base ligands have received attention for their structural diversity [1][2][3][4][5][6] and for various applications and properties, such as electrochemical [7,8] and magnetic properties [9,10] and antiradical effects [11]. Considerable effort has been devoted to the preparation and characterization of multinuclear copper (II) complexes with various Schiff base ligands and bridging dicyanamido [12], azido [13][14][15] and acetate [16] ligands. Trinuclear linear copper(II) complexes have attracted considerable interest [17][18][19][20], but only two of them have been structurally characterized [17,18].…”

“…Trinuclear linear copper(II) complexes have attracted considerable interest [17][18][19][20], but only two of them have been structurally characterized [17,18]. They belong to a series of copper(II) complexes with tetradentate N 2 O 2 Schiff base ligands synthesized by Mitra and his group [5,12,13,17,18] [21,22].…”
