They are isoelectronic, and have similar bonding with a tetrahedral shape (valence bond theory sp3 hybridized) Isolobal refer to frontier orbitals on molecular fragemts such as free radicals not to stable species such a s ammonium cation and tetrahydroborate anion

What is the hyberdization of bh4?

The hyberdization of BH4- is sp3, as boron donates one electron to each of the hydrogen atoms, resulting in four sigma bonds formed by the overlap of the sp3 hybrid orbitals on boron with the 1s orbitals on hydrogen.
