AB  - (Pentamethylcyclopentadieny1)germanium chloride (1) reacts with (tris(trimethylsily1)methyl)lithium to give (pentamethylcyclopentadienyl) (tris(trimethylsily1)methyl)germylene (3) and with (2,4,6-tri-tertbutylpheny1) lithium to yield (pentamethylcyclopentadienyl)(2,4,6-tri-tert-butylphenyl)germylen(4). Both germylenes (3 and 4) are monomeric with a fluxional [eta]2 bonding between the germanium center and the Me5C5 ring. Compound 3 crystallizes in the monoclinic space group P21/c with unit cell dimensions a = 9.954 (1) Å, b = 8.759 (2), Å, c = 29.416 (6) Å, [beta] = 95.05 (2)°, and Z = 4. Complex 4 crystallizes in the monoclinic space group P21/n with unit cell dimensions a = 10.404 (5) Å, b = 13.519 (6) Å, c = 19.203 (10) Å, [beta] = 103.62 (4)°, and Z = 4.
