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.
