On the condensation mechanism of the dioxides of sixth-group elements: an ab initio approach
A quantum mechanical ab initio simulation of XO 2 molecules (X = O, S, Se, Te and Po) and the relevant dimers has been performed. The X-O bond polarity and the bent configuration of the XO 2 species are discussed as factors governing their condensation mechanisms. Three points are emphasized: (i) th...

molecules (X = O, S, Se, Te and Po) and the relevant dimers has been performed. The X-O bond polarity and the bent configuration of the XO

species are discussed as factors governing their condensation mechanisms. Three points are emphasized: (i) the fundamental difference between the constitution of the condensed phases of OO

and SO

, on the one hand, and those of SeO
2
and TeO
2
, on the other; (ii) the occurrence of polymorphism in crystalline TeO

and its absence in crystalline SeO
2
; (iii) the driving forces of the γ-α polymorph transformation in crystalline TeO
