New binuclear Co(II) (1), Ni(II) (2) and Cu(II) (3) complexes of N,N'-(2,2'-azanediylbis(ethane-2,1-diyl))bis(2-aminobenzamide) have been synthesized and fully characterized by various chemical and spectral techniques. The synthesized complexes were irradiated by Co gamma rays to dose value of 100 kGy (hereafter referred to as 1a,2a,3a). Molar conductance, spectral, thermal, magnetic moment measurements, powder X-ray diffraction and solid electrical conductivity measurements were investigated before and after exposure to irradiation.

Controlling the morphology of noble metal-based nanostructures is a powerful strategy for optimizing their catalytic performance. Here, we report a one-pot aqueous synthesis of versatile NiPd nanostructures at room temperature without employing organic solvents or surfactants. The synthesis can be tuned to form zero-dimensional (0D) architectures, such as core-shell and hollow nanoparticles (NPs), as well as nanostructures with higher dimensionality, such as extended nanowire networks and three-dimensional (3D) nanodendrites.

A novel (N6O4) macrocyclic ligand (L) and its Cu(II) complexes have been prepared and characterized by elemental analysis, spectral, thermal (TG/DTG), magnetic, and conductivity measurements. Quantum chemical calculations have also been carried out at B3LYP/6-31+G(d,p) to study the structure of the ligand and one of its complexes. The results show a novel macrocyclic ligand with potential amide oxygen atom, amide and amine nitrogen atoms available for coordination.
