YB2C2 crystallizes in the tetragonal P4_2/mmc space group. The structure is three-dimensional. Y is bonded in a 8-coordinate geometry to eight equivalent B and eight equivalent C atoms. All Y–B bond lengths are 2.75 Å. All Y–C bond lengths are 2.72 Å. B is bonded in a 2-coordinate geometry to four equivalent Y and two equivalent C atoms. Both B–C bond lengths are 1.60 Å. C is bonded in a 2-coordinate geometry to four equivalent Y, two equivalent B, and one C atom. The C–C bond length is 1.43 Å.
