Influence of the non-coordinating alkyl chain type in N -alkylated iminodiacetamides on the stability and structure of their complexes with nickel(II) and cobalt(II)
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
Abstract By the reactions of copper(II) nitrate with N-alkyliminodiacetamide derivatives, RN(CH2CONH2)2 (Rimda; R = Me (methyl), Et (ethyl), Pr (propyl) and Bu (butyl)), four new water-soluble copper(II) complexes were synthesized, namely [Cu(Meimda)2](NO3)2 (1), [Cu(Etimda)2](NO3)2 (2), [Cu(Primda)2](NO3)2 (3) and [Cu(Buimda)2](NO3)2 (4). The complexes were characterized by infrared and UV/Vis spectroscopy
