Abstract
The ethylenediammonium bis tetraiodobismuthate(III) tetrahydrate salt is monoclinic with the following unit cell dimensions:a=7.476(3)Å,b=13.194(3)Å,c=13.916(9)Å, β=95.22(6)°, space groupP21 lc withZ=2. The structure consists of disordered ethylenediammonium cations, water molecules and polynuclear anions in which slightly distored [BiI6]3− octahedra sharingcis edges are interconnected into chains. The [BiI4]− anions are connected through O(W2)−H...I hydrogen bonds, so that infinite two dimensional chains parallel to thea axis with anionic period [BiI4(H2O)]− are formed in the structure. These chains are themselves interconnected by means of the O−H...I and N...O(I) bonds originating respectively from the water molecules and the ethylenediammonium entities, forming a three-dimensional network.
