Abstract: In the title compound, (C₁₁H₂₁N₂)[Er(C₈H₈)₂], the anion displays the sandwich form with planar and parallel cyclooctatetraenyl ligands. The perpendicular distances of the Er atom from the C₈ planes are 1.8809 (7) and 1.8476 (8) Å, with individual Er-C bond lengths in the range 2.596 (2)-2.651 (2) Å. The extended structure consists of chains of alternating anions and cations parallel to (101); residues are connected by C-H interactions and neighbouring formula units are related by an n glide plane.
