Soret) contient au moins deux radicaux métalliques," Comptes rendus hebdomadaires des séances de l'Académie des Sciences, tome 102 (janvier-juin 1886), pp. 1003-04. The name was apparently given because several hundred fractionations ("plusieurs centaines de fractionnements") were required to isolate a sufficient amount of it to test spectroscopically.
