“…1). Along with smaller phosphorus oxides, e.g., P 2 O 4 , P 2 O 5 , and P 2 O 6 [6], cage structures larger than the pentoxide, e.g., P 4 O 18 [7] (from the trioxide and ozone) and P 8 O 12 [8] (the dimer of the trioxide), have also been synthesized and characterized. Synthesis of group V clusters has been accomplished primarily through laser ablation or by quenching vapor in a cold gas, of which both are non-equilibrium techniques.…”

The structure and thermodynamics of the following phosphorus oxide caged clusters were calculated in the gas phase at STP via both the local density approximation (LDA) and a generalized gradient approximation (BLYP) of density functional theory: the experimentally characterized trioxide (P 4 O 6 ) and pentoxide (P 4 O 10 ), and in order of thermodynamic preference, the hypothetical P 24 O 60 , P 8 O 20 , P 24 O 48 , and P 20 O 20 . All of the hypothetical oxides would dissociate to the pentoxide at equilibrium. Secondarily, the LDA calculation of the enthalpy of formation was unexpectedly superior to the BLYP calculation.

Dimerization of Molecular PhosphorusOxides.-The colorless compound P 8 O 12 ·2BH 3 (II) is characterized by 31 P-MAS NMR spectroscopy and mass spectrometry. As revealed by single crystal XRD, (II) crystallizes in the orthorhombic space group Pbca with Z = 8. Its principal building block is a novel P 8 O 12 framework, which originates from the fusion of two P 4 O 6 cages after cleavage of one P-O bond in each cage. -(TELLENBACH, AKBAR; JANSEN, MARTIN; Angew.

P 4 O 6 ·BH 3 , which readily forms from P 4 O 6 and Me 2 S·BH 3 in a stoichiometric reaction, dimerizes spontaneously at −30°C in a concentrated toluene solution resulting in the crystallization of P 8 O 12 ·2BH 3 (1). The synthesis of 1 represents the first selective interconnection of molecular phosphorus chalcogenides leading to the formation of a new, flexible P 8 O 12 cage. The thermodynamic driving force for the dimerization reaction results from a gain of enthalpy due to enhanced P−O double-bond contributions and a relief of angular strain. In terms of kinetics, the behavior of P 4 O 6 ·BH 3 , differing from that of other P 4 O 6 derivatives, is caused by the low π-donor
