520 3 |a DFT PBE0/cc-pVDZ method was applied to calculate the structural parameters of C60C(CCH)2, C60H2, C60H(t-Bu), C60HCCH, C60(CCH)2 molecules, and of the corresponding carbanions. The length of the carbon-carbon fullerene after the binding with the diethynylcarbene, atoms and/or radicals increases to 1.565, 1.577, 1.587, 1.591, 1.616 Å respectively, but in the relatively stable fulleride anions C60(t-Bu)− and C60CCH− this bond has a normal length of 1.525 Å. Acetylenide anions C60HCC−, C60(CCH)CC−, and C60C(CCH)CC− are weaker as Brønsted bases than the hypothetical dodecahedrane analogs, but stronger than C60(t-Bu)−, C60CCH−, and C60H− fulleride anions where the charge is localized on the fullerene core.
