The infrared absorption spectra of magnesium fluoride and magnesium chloride isolated in solid krypton and argon matrices have been investigated from $240-4000cm-1$. The molecules were generated in a high temperature cell and trapped at liquid $H2$ and He temperatures. The spectrum of $MgF2$ indicates that the apex angle F---Mg---F is $160\circ \pm 20\circ$. Complete assignment and other details will be discussed.
