“…Several bismuth oxide−sulfate phases have been prepared from the pyrolysis of Bi 2 (SO 4 ) 3 . Bi 2 O 2 SO 4 has been reported to be the first product, , and subsequent pyrolysis results in additional loss of SO 3 to form two different phases with compositions Bi 2 O 3 ·0.9SO 3 [Bi 26 O 27 (SO 4 ) 12 ] and Bi 2 O 3 ·0.67SO 3 [Bi 14 O 16 (SO 4 ) 5 ] …”

A new bismuth oxide sulfate of stoichiometry Bi 14 O 20 (SO 4 ) has been synthesized from thermal treatment of an intimate mixture of R-Bi 2 O 3 and (NH 4 ) 2 SO 4 in the mole ratio 1:0.14, and its structure determined using a combination of electron diffraction, X-ray powder diffraction, and neutron powder diffraction. The body-centered tetragonal unit cell (I4/m; a ) 8.664(1) Å, c ) 17.282(2) Å) is a commensurate superstructure of the cubic fluorite subcell of δ-Bi 2 O 3 (a 0 ): a ) ( 10/2)a 0 , c ) 3a 0 . The structure contains discrete sulfate anions at the unit cell corners and body center, and a Bi-O framework of linked BiO 4 e (e ) lone pair of electrons) square pyramids and trigonal bipyramids. The square pyramids are aggregated into clusters of composition Bi 6 O 8 , comprising O 2ions arranged in the form of a cube, the faces of which are capped by Bi 3+ ions. In contrast, the trigonal bipyramids are corner linked to form layers perpendicular to [001]. The structure is thought to represent just one of several related phases in this system.

The first bismuth borosulfate (H 3 O)Bi[B(SO 4) 2 ] 4 is only the second featuring a three-dimensional anion, the first tectosilicate-analogous borosulfate synthesised solvothermally without a precursor (from Bi(NO 3) 3 •5 H 2 O and B(OH) 3 in oleum); moreover, it is the first comprising two differently charged cations and crystallises in a new structure type in space group I4 (no. 82) (a = 11.857(1), c = 8.149(1) , 1947 refl., 111 param., wR2 = 0.037), confirmed by a second harmonic generation (SHG) measurement. The B(SO 4) 4 supertetrahedra are connected via all four sulfate tetrahedra resulting in a threedimensional anion with both H 3 O + and Bi 3+ cations in channels. Additionally, the crystal structure of a further bismuth borosulfate, Bi 2 [B 2 (SO 4) 6 ], is elucidated crystallising isotypically to the rare-earth borosulfates R 2 [B 2 (SO 4) 6 ] in space group C2/c (No. 15) (a = 13.568(2), b = 11.490(2), c = 11.106(2) , 3127 refl., 155 param., wR2 = 0.035). Moreover, the optical and thermal properties of both compounds are discussed.

“…Among these oxosalts, the Bi 3+ –O 2– –SO 4 2– ternary system included 10 different bismuth oxosulfates ,,− in addition to Bi 2 O 3 and Bi 2 (S 2 O 7 ) 3 . The Bi:SO 4 ratio in each compound varies from 0.33:1 to 14:1.…”

“…Almost all of them were obtained after pyrolysis of Bi 2 (SO 4 ) 3 . Bi 2 O 2 SO 4 was the first reported in 1965. − With the loss of additional SO 3 , the subsequent pyrolysis products changed into (Bi 26 O 27 )(SO 4 ) 12 and (Bi 14 O 16 )(SO 4 ) 5 . At this stage, two important compounds with lower SO 4 content were reported: (1) (Bi 8 O 11 )(SO 4 ) characterized by a complex low temperature phase and defected fluorite structure high temperature phase and (2) (Bi 14 O 20 )(SO 4 ) which adopts a commensurate superstructure of the cubic fluorite subcell .…”

Investigation of New Alkali Bismuth Oxosulfates and Oxophosphates with Original Topologies of Oxo-Centered Units

Two new alkali bismuth oxosulfates, [Bi12O15]Li2(SO4)4 (I) and [Bi7K2O8]K(SO4)4 (II), have been synthesized by heating a mixture of Bi2O3, CuSO45H2O, and A2CO3 (A = Li, K), and characterized by single crystal XRD, transmission electron microscopy, and multiphoton SHG and IR spectroscopy. In the above formula the [BixOy] subunits denote the 3D-porous (I) or 1D-columnar (II) polycationic host-lattice formed of edge-sharing OBi4 or O(Bi,K)4 oxocenterd tetrahedra. The SO4(2-) groups and alkali ions are arranged into channels in the interstices leading to original opened crystal structures for these two first reported alkali oxo-bismuth sulfates. The strong adaptability of the oxocentered framework is demonstrated by the possibility of preparing single crystals of [Bi8.73K0.27O8]K1.54(PO4)4 (III) whose crystal structure is similar to those of II with disorder between OBi4 and O(Bi3,K) tetrahedra and different channel occupancy due to the aliovalent replacement of SO4(2-) for PO4(3-).
