Abstract
The 1,2,3,4-tetraphenyl-shielded sodium cyclopentadienide, Na+[HC5(-)( C6H5)(4)], demonstrates essential facets of structure-determining cati on solvation. The following solvent-shared or solvent-separated ion mu ltiples have been crystallized from the respective aprotic ether solut ions and structurally characterized: [(C29H21-)Na+(THF)(7/2)], [(C29H2 1-)Na+(DME)(2)], [(C29H21-)](-)[Na+(diglyme)(2)](+), [(C29H21-)](-)[Na +(triglyme)(2)](+) and, from 18-crown-6 solution, the novel tripeldeck er ion triple, a+(18-crown-6)Na+(18-crown-6)Na+(18-crown-6)](++), whic h contains two Na+ counter cations between three 18-crown-6 discs. The structures, discussed in comparison with literature data and based on MNDO calculations, demonstrate the essential effects of Na+ counter c ation solvation by various ether ligands.
