Abstract

The structure of synthetic disodium magnesium disulfate deca-hydrate at 180 K consists of alternating layers of water-coordinated [Mg(H2O) 6]2+ octa-hedra and [Na2(SO4) 2-(H2O)4]2- sheets, parallel to [100]. The [Mg(H2O)6]2+ octa-hedra are joined to one another by a single hydrogen bond, the other hydrogen bonds being involved in inter-layer linkage. The Mg2+ cation occupies a crystallographic inversion centre. The sodium-sulfate sheets consist of chains of water-sharing [Na(H2O)6]+ octa-hedra along b, which are then connected by sulfate tetra-hedra hrough corner-sharing. The associated hydrogen bonds are the result of water-sulfate inter-actions within the sheets themselves. This is believed to be the first structure of a mixed monovalent/divalent cation sulfate deca-hydrate salt.
