Nickel(II) chelates with N-phenethyl-iminodiacetate(2-)-like ligands: Synthesis, crystal structure and spectroscopic studies.

The stoichiometric reactions between Ni(II) hydroxy-carbonates and N- p -(R)-H 2 pheida derivatives (R =  MeO or F for  MOpheida or Fpheida respectively) yield two novel binary compounds [Ni(MOpheida)(H 2 O) 3 ] ( 1 ) and [Ni(Fpheida)(H 2 O) 3 ] ( 2 ). The crystal of compounds 1 and 2 are iso-type; space group P2 1 /c. Our crystallographic results revealed that both studied metal-chelates have  molecular structure and the used p-R substituents on the pheida skeleton yield the same structural features. The IDA moiety of pheida-like ligands exhibit the fac -NO 2 conformation ( 1 & 2 ). Crystal structure of H 2 Fpheida free acid have also been reported herein.
