'''Selenium oxydichloride''' is the ] with the formula SeOCl<sub>2</sub>. It is a liquid with a high dielectric constant (55) and high specific conductance, and for these reasons is an attractive solvent. Structurally, it is a close chemical relative of ] SOCl<sub>2</sub> and ] as a donor solvent. |
