title: Stable G-quadruplex structure in a hydrated ion pair: cholinium cation and dihydrogen phosphate anion.
abstract: A combination of cholinium cations and dihydrogen phosphate anions is indispensable for the G-quadruplex structure regardless of water content. No G-quadruplex structure was observed in most salts even containing either cholinium cations or dihydrogen phosphate anions.
