Quantum chemical and chemotopological study of fourth row monohydrides

We obtained a chemotopological classification of fourth period monohydrides based on their B3LYP/6-311+G(3df,3pd) properties. This classification has a strong chemical sense and is similar to that of Rayner-Canham, based on experimental data. This figure presents the PC1-PC2-PC3 space with the ionic IH, transition-metal TM and covalent CH hydrides.
