coordination environment around the nickel(II) and cobalt(II) ions in the structures of the complexes consists of two O,N,O′-tridentate N-arylalkyliminodiacetamide ligands arranged in a fac-position, resulting in the formation of trans isomers in all cases. Hydrogen bonds link cations and anions in 3D networks with alternating layers of cations and anions. The molecular geometry and infrared spectra of these
