The formula of a noble gas species which is isostructural with \(BrO_3^-\) is:

\(XeOF_4\) \(XeF_2\) \(XeO_3\) \(XeF_4\)

\(XeO_3\)

\(XeO_3\)​ is isostructural with \(BrO_3^−\)​. It has a pyramidal shape due to \(sp^3\) hybridization with tetrahedral geometry in which one position is occupied by a lone pair.
