Two better than one! The structural distortions in a bis(cyclopropyl) heterobimetallic lithium yttrium complex can be interpreted as two types of CC agostic interactions (see structure), one with a more covalent character with Y, the other with a more electrostatic character with Li. The CC agostic interaction with Y is reinforced by a CH agostic interaction.
