The title compounds both comprise a tetra­butyl­ammonium cation, a halide anion and an  ortho -phenyl­ene bis-urea mol­ecule. Each halide ion shows four N—H⋯ X  ( X  = Cl or Br) inter­actions with two urea receptor sites of different bis-urea moieties. A crystallographic inversion centre leads to the formation of a 2:2 arrangement of two halide anions and two bis-urea mol­ecules.
