Abstract
The title compound, [NH3(CH2)2NH3][Mg(SO4)2(H2O)4], was synthesized by the slow evaporation method. Its crystal structure can be described as an alternate stacking of inorganic layers of tetraaquabis(sulfato-

combines some properties of an inorganic material (or a molecule), and some
properties of an organic molecule (or a polymer). This symbiosis between two
worlds of chemistry too long regarded as opposites can also lead to completely
new properties, and opens a wide field of investigations for the chemist. The
applications of these "new" materials cover diverse areas as the properties of
strength, optics, ferroelectricity and ferroelasticity, electronics and ionic
solid ··· Recently, we reported some new organic-inorganic hybrid solids
composed of 3d transition metal, sulfate groups and protonated diamine (Rekik
<italic>et al.</italic>, 2005; Naïli, <italic>et al.</italic>, 2006; Rekik <italic>et
al.</italic>, 2007;
Yahyaoui <italic>et al.</italic>, 2007; Rekik <italic>et al.</italic>, 2008; Rekik
<italic>et al.</italic>,
2009). In the field of our investigations in the organic-inorganic
hybrid
materials, we report here the chemical preparation and the structural
characterization of a new magnesium ethylenediammonium
bis(sulfate)tetrahydrate,[NH<sub>3</sub>(CH<sub>2</sub>)<sub>2</sub>NH<sub>3</sub>][Mg(SO<sub>4</sub>)<sub>2</sub>(H<sub>2</sub>O)<sub>4</sub>]. The
title compound is isostructural with the manganese, iron and cobalt related
phases (Chaabouni <italic>et al.</italic>, 1996; Held <italic>et al.</italic>, 2003; Rekik
<italic>et
al.</italic>, 2008). As it can be seen in figure 1, the asymmetric unit of
the
title compound contains only one magnesium atom located at a symmetry centre,
only one sulfate tetrahedron and ethylenediammonium cation lying about
inversion centre. The Mg(II) central atom is octahedrally coordinated by one
oxygen atom of sulfate group, two water molecules and the corresponding
centrosymmetrically located atoms. Each octahedron around Mg shares two oxygen
with two sulfate groups to form trimeric units, [Mg(SO<sub>4</sub>)<sub>2</sub>(H<sub>2</sub>O)<sub>4</sub>]<sup>2-</sup>.
The negative charge of the inorganic part is compensated by ethylenediammonium
cations which are located on inversion centres in the inorganic framework
cavities. The structure cohesion and stability are assured by two types of
hydrogen bonds, OW—H···O and N—H···O. Figure 2 shows that the structure
can be described as an alternation between organic and inorganic layers along
the crystallographic <italic>b</italic> axis.</p></sec><sec id="experimental"><title>Experimental </title><p>Single-crystals of the title compound were grown by slow evaporation at room
