Popis: Thermodynamic data for gaseous SiF2 and SiCl2 known from literature show that these binary subhalides are formed nearly quantitatively at 1376 °C and 1076 °C, respectively, as products of the reaction of elemental silicon with SiF4 or SiCl4 at 110 -2 mbar. Ap- plying the co-condensation technique SiF2 as well as SiCl2 can be trapped at -196 °C and prepared in synthetic scale. Herein, first analy- sis of metastable SiF2 and SiCl2 solutions are presented, showing that
