Properties: Colorless gas. Intensely poisonous. Disagreeable odor. mp -88°. bp -18.4°. d 2.204 g/ml at bp. Heat of formation +34.68 kcal/mole: Gunn, Green, J. Phys. Chem. 65, 779 (1961). Thermally less stable than arsine. Dec slowly on standing at room temp. Quickly destroyed at 200°. The decomposition products are hydrogen and metallic antimony, generally deposited in the form of a mirror. The gas is slightly sol in water. Freely sol in alcohol, carbon disulfide, other organic solvents. Lethal concn in air for mice: about 100 ppm.
