Physical Properties

Trimethylantimony is a colorless liquid, insoluble in water, soluble in benzene .

Chemical Properties

It is oxidized by oxygen with autoignition:

{\mathsf {2Sb(CH_{3})_{3}+O_{2}\ {\xrightarrow {}}\ 2Sb(CH_{3})_{3}O}}

{\ displaystyle {\ mathsf {2Sb (CH_ {3}) _ {3} + O_ {2} \ {\ xrightarrow {}} \ 2Sb (CH_ {3}) _ {3} O}}}

{\mathsf {2Sb(CH_{3})_{3}+O_{2}\ {\xrightarrow {}}\ 2Sb(CH_{3})_{3}O}}

Reacts with halogens:

{\mathsf {Sb(CH_{3})_{3}+Cl_{2}\ {\xrightarrow {}}\ Sb(CH_{3})_{3}Cl_{2}}}

{\ displaystyle {\ mathsf {Sb (CH_ {3}) _ {3} + Cl_ {2} \ {\ xrightarrow {}} \ Sb (CH_ {3}) _ {3} Cl_ {2}}}}

{\mathsf {Sb(CH_{3})_{3}+Cl_{2}\ {\xrightarrow {}}\ Sb(CH_{3})_{3}Cl_{2}}}

and alkyl halogens:

{\mathsf {Sb(CH_{3})_{3}+CH_{3}I\ {\xrightarrow {}}\ Sb(CH_{3})_{4}I}}

{\ displaystyle {\ mathsf {Sb (CH_ {3}) _ {3} + CH_ {3} I \ {\ xrightarrow {}} \ Sb (CH_ {3}) _ {4} I}}}

{\mathsf {Sb(CH_{3})_{3}+CH_{3}I\ {\xrightarrow {}}\ Sb(CH_{3})_{4}I}}
