New series of metal ions complexes have been prepared from the new ligand [2,2′‐(5,5‐dimethylcyclohexane‐1,3‐diylidene)bis(azan‐1‐yl‐1‐ylidene)dibenzoic acid] derived from 5,5‐dimethylcyclohexane‐1,3‐dione and 2‐aminobenzoic acid. Accordingly, mono‐nuclear Ni(II), Pd(II), Re (II), and Pt(IV) complexes were prepared by the reaction of previous ligand with NiCl 2 .6H 2 O, PdCl 2 , ReCl 5 , and H 2 PtCl 6 .6H 2 O, respectively. The compounds have been characterized by Fourier‐transform infrared (FTIR), ultraviolet–visible (UV–vis), mass, H 1 ‐, and C 13 ‐nuclear magnetic resonance (NMR) spectra and thermo gravimetric analysis (TGA) curve, Bohr magnetic (B.M.), elemental microanalyses, metal ions, chloride containing, and molar conductance. These reviews uncovered octahedral geometries for the Re(V) and Pt (IV) complexes and tetrahedral for Ni (II) complex and square planer for Pd (II) complex. The investigation of complexes development by means at molar proportion and occupation strategy in DMF solution has been researched, and results were reliable to those found in the solid complexes with a proportion of (M:L) as (1:1).
