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

Abstract

The stoichiometric reactions between Ni(II) hydroxy-carbonates and N-p-(R)-H₂pheida derivatives (R =  MeO or F for  MOpheida or Fpheida respectively) yield two novel binary compounds [Ni(MOpheida)(H₂O)₃] (1) and [Ni(Fpheida)(H₂O)₃] (2). The crystal of compounds 1 and 2 are iso-type; space group P2₁/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-NO₂ conformation (1 & 2). Crystal structure of H₂Fpheida free acid have also been reported herein.
