Excess molar enthalpies at the temperature 298.15 K were measured for CH2)n-2CH3}, (n = 10, 12), using a Calvet microcalorimeter. The experimental results were compared with those calculated by using the Nitta-Chao, UNIFAC I, and UNIFAC II models.
The title compound has been prepared in good yield by the reaction of [Me 2 GaOMe] 3 (Me = CH 3 ) with HP(SiMe 3 ) 2 in toluene (ratio 1 : 1,1) and purified by crystallization from pentane or toluene, respectively. This organogallium compound forms (Ga±P) 3 ring skeletons with one Ga±P(SiMe 3 ) 2 ±G
