Yes, in NaBr crystal, each ion is octahedrally surrounded by ions of opposite charge. The positive Na+ ions and the negative Br- ions in the crystal are in fcc crystal lattice. The Na+ occupy the octahedral positions in the Br- sub-lattice and the Br- occupy the octahedral positions in Na+ sub-lattice.

NaBr has the sodium chloride (rock salt) structure where each anion (Cl^-) is surrounded by six cations (Na^+) in an octahedral configuration and likewise each cation (Nal^+) is surrounded by six anions (Cl^-) also in an octahedral array.
SO THANKS PLZZZZZZZZZZZZZZZZZZZZ.
