Description
Summary:Crystals of the title salt, [Na(C6H14O3)2]2(C26H20), were grown from a tetrahydrofuran/diglyme/Et2O solvent mixture [diglyme is 1-methoxy-2-(2-methoxyethoxy)ethane]. The cations and dianion are separated in the crystal structure, unlike in the other three structurally characterized dialkali metal tetraphenylethylene 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.
