1938 C. Palache in Amer. Mineralogist 23 34 Leightonite, as the new species will be named, is triclinic, as shown by optical examination.

1962 Canad. Mineralogist VII. 276 It is interesting to note that leightonite has a chemical homologue—polyhalite, K₂Ca₂Mg(SO₄)₄.2H₂O.

1963 Acta Crystallogr. A. 15 10/1 Leightonite, K₂Ca₂Cu(SO₄)₄.2H₂O, is triclinic, but it is pseudo-orthorhombic (face-centred) to the extent that no departure from 90° has been found in the angles of the unit cell as determined by the usual X-ray diffraction techniques.
