Bottom Line: The asymmetric unit contains one [Na(diglyme)2](+) cation and one half of the [Ph2CCPh2](2-) dianion.C-C bond-length redistribution displays that excessive electron density of the dianion is predominantly located at the C atoms of a former double bond and at all eight ortho positions.The twin operation is a twofold rotation around the a axis.

ABSTRACT
Crystals of the title salt, [Na(C6H14O3)2]2(C26H20), were grown from a tetra-hydro-furan/diglyme/Et2O solvent mixture [diglyme is 1-meth-oxy-2-(2-meth-oxy-eth-oxy)ethane]. The cations and dianion are separated in the crystal structure, unlike in the other three structurally characterized dialkali metal tetra-phenyl-ethyl-ene salts. The asymmetric unit contains one [Na(diglyme)2](+) cation and one half of the [Ph2CCPh2](2-) dianion. The latter lies on a twofold rotation axis. C-C bond-length redistribution displays that excessive electron density of the dianion is predominantly located at the C atoms of a former double bond and at all eight ortho positions. The studied crystal was a twin, with the ratio of two major components being 0.2143 (9):0.7857 (9). The twin operation is a twofold rotation around the a axis.
