A supramolecular double sulfate salt with a lamellar type: crystal structure and thermal behavior.

The synthesis of a series of supramolecular double sulfate salts using transition metals and the aromatic amine α-methylbenzylamine afforded an unexpected hybrid lamellar structure type. (C8H12N)2[M(H2O)4(SO4)2]·2H2O (M = Fe to Zn) crystallizes with a monoclinic structure (S.G.
