Template Synthesis of Fe(III) and Cr(III) Acyclic Complexes Derived from Diacetyl or Benzil and 1‐Amino‐5‐benzoyl‐4‐phenyl‐1H‐pyrimidine‐2‐one

Abstract The template synthesis of diacetyl or benzil and 1‐amino‐5‐benzoyl‐4‐phenyl‐1H‐pyrimidine‐2‐one in the presence of Fe(III) and Cr(III) results in the formation of acyclic complexes of the types [ML1X2]X, [ML2X2]X, and [Fe2(L1)2Cl4]Cl2 · H2O, where M = Fe(III), Cr(III), L1 (benzyl derivative), or L2 (diacetyl derivative) are N2O2/ONO acyclic ligands and X = Cl, NO3). The complexes have been characterized by elemental analyses, molar conductance, magnetic measurements, IR, and UV/VIS spectral studies.
