“…Materials containing antimony have received increasing attentions mainly due to their interesting physical properties and potential applications in nonlinear optics, electrochemistry and photocatalysis, e. g., in recent years [1–8] . In the antimony compounds, a number of irregular SbO n (n=3, 4, 5, 6) coordination geometries can be found, such as trigonal‐pyramidal SbO 3 , seesaw SbO 4 , square‐pyramidal SbO 5 , or distorted octahedral SbO 6 [9–13] . Benefiting from the diversity and flexibility of its structure, Sb−O units can construct various novel crystal structures by selecting functional building blocks to exhibit special physical properties.…”

Two new antimony (III) tellurite sulfates [Sb 2 (TeO 4 )](SO 4 ) ( 1) and [Sb 2 (TeO 3 ) 2 ](SO 4 ) (2) were successfully synthesized through a conventional hydrothermal method and their crystal structures were determined by X-ray single crystal analysis.[Sb 2 (TeO 4 )](SO 4 ) crystallizes in the triclinic space group Pī (No. 2) with lattice parameters a = 5.572(2), b = 7.247(2), c = 9.540(3) Å, V = 358.5( 2) Å 3 , and Z = 2, while [Sb 2 (TeO 3 ) 2 ](SO 4 ) crystallizes in the orthorhombic space group Pbca (No. 61) with lattice parameters a = 7.368(2), b = 14.571(3), c = 16.521(3) Å, V = 1773.7(6) Å 3 , and Z = 8. The structure of [Sb 2 (TeO 4 )](SO 4 ) features a three-dimensional framework, composed of [SbO 4 ] trigonal bipyramids and [TeO 4 ] polyhedra to form a cationic 2 1[Sb 2 (TeO 4 )] 2 + corrugated cationic layers along [100], linked by SO 4 2À anions. [Sb 2 (TeO 3 ) 2 ](SO 4 ) forms a three-dimensional framework consisting of two dimensional wrinkled layers of 2 1[Sb 2 (TeO 3 ) 2 ] 2 + that are linked by SO 4 2À anions. The band gaps of 4.16 eV and 3.72 eV for [Sb 2 (TeO 4 )](SO 4 ) and [Sb 2 (TeO 3 ) 2 ](SO 4 ) respectively are estimated from the solid state UV-vis-NIR diffuse reflectance spectra. Thermal analysis indicated that both compounds are thermally stable up to about 500°C. The electrochemical specific capacity of [Sb 2 (TeO 4 )](SO 4 ) was determined to 245 mA h g À 1 on the first cycle in a Li-ion half-cell, the capacity remains at about 106 mA h g À 1 after 500 cycles.

Nanoporous aluminosilicate zeolites find technological applications in areas such as catalysis, separations, and ion exchange. [1] After Flanigen et al. reported a series of openframework aluminophosphates (AlPO 4 s), [2] others successfully incorporated transition and other main group metals into open frameworks. [3] Unlike the zeolites and many AlPO 4 s, which are based upon corner-sharing [XO 4 ] tetrahedra, many of the newer materials are based on other polyhedra that give rise to new topologies. For example, several open-framework tin(ii) phosphates [4] were prepared in which the stereochemically active electron lone pair associated with each Sn II center leads to trigonal [SnO 3 ] and square pyramidal [SnO 4 ] units. One of these materials [4f] is truly nanoporous and exhibits reversible dehydration and ion-exchange properties. We therefore extended the search for open frameworks into the Sb 2 O 3 /P 2 O 5 system.Open frameworks containing Sb III include the antimony(iii) sulfides [5] and the mineral cetineite and related synthetic phases. [6] While a number of Sb V [7] and mixed-valent Sb III /Sb V [8] phosphates have been made, until recently the only known materials based solely on [Sb III O x ] and [P V O 4 ] polyhedra were condensed SbPO 4 [9] and layered SbO(H 2 PO 4 )´H 2 O. [10]Layered antimony(iii)fluoride phosphates have also been synthesized: KSbF 2 (HPO 4 ) [11] and MSbFPO 4´n H 2 O (M NH 4 , Na, K, Rb, Cs, CN 3 H 6 , n 0 ± 1.5) [12, 13] , as well as a chain-type structure: CsSbF 3 (H 2 PO 4 ). [13] The three-dimensional structure of a new Sb III -based material, NaSb 3 O 2 (PO 4 ) 2 , [14] although not microporous, suggested that Sb III could be incorporated into an open framework phosphate. By using a structure-directing agent (SDA) under hydrothermal synthesis conditions [15] we synthesized the material described below.The asymmetric unit of [H 3 N(CH 2 ) 2 NH 3 ] 1.5 [(SbO) 2 (SbF) 2 -(PO 4 ) 3 ] contains 29 crystallographically independent nonhydrogen atoms ( Figure 1). As in many other open frameworks for which fluorine is used as a mineralizer, [16±19] fluorine is incorporated into the structure. This framework is based upon a network containing: 1) pseudo-octahedral [SbO 5 E] and [SbO 4 FE] units (E lone pair), 2) pseudo-trigonal-bipyramidal [SbO 4 E] and [SbO 3 FE] units (the lone pairs of electrons occupy axial and equatorial positions in the [*] Prof.
