Ce$_{3}$Au$_{3}$Sb$_{4 }$has diverging specific heat coefficient at low temperature in a semiconducting state, a property which can be approached differently within the Kondo and band insulator viewpoints. Sample sensitivity here presents difficulty for determining the intrinsic behavior of this system. We will present pressure and powder neutron scattering experiment data in addition to its basic physical properties in order to discuss the underlying physics. This work has been supported by NSF-DMR-0503360.
