The present scientific contribution aims to investigate computationally the effects of substitution and substituent position on the reactivity of a series of salicylideneaniline derivatives ligands containing 13 molecules. Global reactivity parameters such as the EHOMO, ELUMO, gap energy, electronegativity, chemical hardness, chemical softness, electrophilicity index, and molecular electrostatic potential analysis (MESP) have been calculated at DFT/B3LYP/TZP level of theory and then well discussed to give valuable explanations for the effects of substitution and substituent position on the reactivity of the studied ligands.

Penta and tetra coordinated germanium complexes have been synthesized from N,N’-bis(2-pyridyl)pyridine-2,6-dicarboxamide (H2L) and N-(pyridine-2-yl)picolinamide (HL1) with dialkyl/aryl and trialkyl/aryl germanium halides in 1:1 molar ratios. The molecular structures and electronic properties of complexes were well analyzed by GAUSSIAN 03 suit of programs. The transannular bonding observed in penta coordinated complexes have been well established by natural bond orbital, Wiberg bond index and molecular electrostatic potential analysis
