A new N,N’-chelating ligand, diethyl-N,N’-bis(p-tolyl)malonimidate 1, has been prepared and treated with organometallic complexes including: trimethylaluminum (product 2), diethylzinc (product 3), and a chlorodicarbonylrhodium(I) dimer (product 4). Compounds 1-4 have been characterized by IR, NMR and elemental analyses, as well as by single crystal X-Ray diffraction. A computational investigation was performed to study the stabilization of such low-valent main-group species. It was found experimentally that compound 3 dimerizes in a face-to-face conformation. A long, C–Zn π-type interaction was observed both crystallographically and in an Atoms in Molecules (AIM) analysis of the wavefunction of the gas phase dimer.
