Synthesis, Characterization and Antibacterial Properties of Complex [Ag(SCN)(2-NH2py)]

“…Complexes with 2-,3-or 4-NH2py ligands show that NH2py tends to act as a monodentate ligand by binding to the central atom via the N pyridine ring. Complexes that have been reported such as [Ni(NCS)2(2-NH2py)2.C4H10O] [7], {∞[Cd(µ-SCN)2(4-NH2py)2]} [8], [Cu(SCN)2(x-NH2py)2] (x=2,3, or 4) [4], and [M(3-NH2py)2(dca)2] (M=Mn2+, Cu2+,Cd2+, or Co2+; dca = dicyanamide) [1,[9][10][11], [AgL(x-NH2py)2] [12][13][14][15][16] demonstrated the formation of polymer complexes via bridge formation by bidentate ligands such as dicyanamide, thiocyanate and azide. Several other complexes with monodentate ligands such as Cl¬ such as…”

Synthesis, Structural Determination and Antibacterial Properties of Zinc(II) Complexes Containing 4-Aminopyridine Ligands

“…Moreover, complexes with aminopyridine have been studied due to their potential as antibacterial agents [2][3][4]. Complexes with aminopyridine ligand such as poli-[Cu(NCS) 2 (x-NH 2 py) 2 ] [2], [Cd(μ-L) 2 (NH 2 py) 2 ] (L = SCN − , dca, N 3 − ) [5][6][7], [Mn(L) 2 (3-NH 2 py) 2 ] (L = dca, SCN − ) [5][6]8] and [Co(dca) 2 (2-NH 2 py) 2 ] [3] have shown to form a polymeric structure through bidentate ligands such as dicyanamide ion (dca), nitride ion (N 3 − ) and ambidentate ligand such as SCN − . The polymeric complexes can be obtained as long as octahedral coordination of the metal center is preserved, whereas complex compounds with tetrahedral geometry such as [Zn(NCS) 2 (x-NH 2 py) 2 ] (x = 2 and 3) [9][10], [Zn(CN) 2 (x-NH 2 py) 2 ] [11], [MCl 2 (x-NH 2 py) 2 ] (M = Zn(II), Co(II) [4,12] tend to form monomeric complexes [9,[13][14].…”
