A drawing of the crystallographically determined structure of Tb2@C79N, Only the symmetrical molecular site with 0.050 fractional occupancy is shown. At this site there is a crystallographic mirror plane which lies perpendicular to the plane of the paper and bisects the line between the two terbium atoms. The Tb1-Tb1A separation in 3.9020(10) and the occupancy of Tb1 corresponds to 0.43 of the total Tb content.
