In diethylammonium hexachlorobismuthate(III) the Bi atoms form a slightly distorted cubic I arrangement, i.e. they occupy the corners and the midpoint (owing to the c-glide plane) of the pseudo-cubic rhombohedral unit cell defined by the transformation a' 1 =-1/3a 1 +1/3a 2 +1/3c, a' 2 =-1/3a 1 -2/3a 2 +1/3c, a' 3 =2/3a 1 +1/3a 2 +1/3c; each Bi atom is surrounded octahedrally by six Cl atoms. The octahedron occurs in two different orientations according to the c-glide plane. The centres of the organic groups are close to the midpoints of the edges and the faces of the I-centred cubic cell. The isolated octahedra are connected to form a three-dimensional framework by hydrogen bonding via three symmetrically equivalent atoms Cl(1), which form an octahedral face |
