Detailed crystal structures of the tetragonal RB2C2 (R=La, Ce, Pr, Nd, Tb, Dy, Ho, Er, Tm and Lu) compounds which include the antiferroquadrupolar ordering materials, DyB2C2 and HoB2C2, have been investigated by neutron powder diffraction technique. RB2C2 are crystallised in the same LaB2C2 type crystal structure with P4/mbm symmetry. The structure of the B C network which consists of non-regular squares and octagons are nearly the same in the system except slight rotation as rare earth atoms become heavier.
