Abstract

Detailed crystal structures of the tetragonal RB<FONT SIZE="-1"><SUB>2</SUB></FONT>C<FONT SIZE="-1"><SUB>2</SUB></FONT> (R=La, Ce, Pr, Nd, Tb, Dy, Ho, Er, Tm and Lu) compounds which include the antiferroquadrupolar ordering materials, DyB<FONT SIZE="-1"><SUB>2</SUB></FONT>C<FONT SIZE="-1"><SUB>2</SUB></FONT> and HoB<FONT SIZE="-1"><SUB>2</SUB></FONT>C<FONT SIZE="-1"><SUB>2</SUB></FONT>, have been investigated by neutron powder diffraction technique. RB<FONT SIZE="-1"><SUB>2</SUB></FONT>C<FONT SIZE="-1"><SUB>2</SUB></FONT> are crystallised in the same LaB<FONT SIZE="-1"><SUB>2</SUB></FONT>C<FONT SIZE="-1"><SUB>2</SUB></FONT> 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.
