Özet
The electronic structure, harmonic vibrational frequencies, thermochemical analysis, nucleus independent chemical shifts (NICS) and HOMO-LUMO gaps of the MC4X4 (M = alkaline earth metals, X = O, S) species have been investigated using ab initio calculations. Calculations show metalated squarate species have the aromatic character, but metalated tetrathiosquarate species are anti-aromatic. Also, NICS and HOMO-LUMO gaps values predict metalation increases aromaticity MC4O4 species and decreases anti-aromaticity of MC4S4 species. © 2007 Taylor & Francis.
