It is shown that the apatite phases of composition Ca 10-x Na x (PO 4 ) 6-x (SO 4 ) x F 2  crystallize in a monoclinic unit cell, which is related to those of pure fluoroapatite by doubling the b-parameter. Some comparisons with related systems are made and a possible explanation for the origin of the small monoclinic distortion is advanced
