sextate

De Toni’s placing the quadrate form in Amphitetras and the sextate in Nothoceratium is of course indefensible.

The room temperature magnetic moments of these complexes were determined by the Gouy method and the values are in the range 5.7—5.9 B.M. (Table), indicative of the presence of five unpaired electrons and the sextate ground state level in these complexes.
