KSbB2O6 and BaSb2B4O12: Novel Boroantimonates with 3D Anionic Architectures Composed of 1D Chains of SbO6 Octahedra and B2O5 Groups

“…Hence the SbO 6 octahedron is only slightly distorted. These bond distances and angles are close to those reported in K 3 BSb 4 O 13 . Both B atoms of the B 2 O 5 group are 3-coordinated with a planar triangular geometry and B–O distances are in the range of 1.343(7)–1.407(7) Å.…”

“…It is interesting to compare the structure of KSbB 2 O 6 with that of K 3 BSb 4 O 13 , which is an antimony-rich phase, its structure features a novel three-dimensional network composed of hexagonal bronze-like 2D (Sb 3 O 9 ) layers that are cross-linked alternatively by edge-sharing Sb 2 O 10 dimers and BO 3 triangles, forming 1D tunnels of Sb 8 8-MRs and Sb 4 B 2 6-MRs along both a and b axes, which are filled by K + ions.…”

“…Recently, our group discovered a series of open framework materials that contain both a borate and selenite group with a lone pair, among which NLO-active Se 2 B 2 O 7 features a neutral three-dimensional (3D) framework composed of B 2 O 7 corner-sharing with Se(IV)O 3 groups, whereas K 2 Se 3 B 2 O 10 , ASeB 3 O 7 (A = Na, K), and Li 2 SeB 8 O 15 display 1D, 2D, and 3D anionic frameworks, respectively . Unlike metal borophosphates and boroarsenates, little is known about boroantimonates and boroantimonites . The only structurally characterized stoichimetric boroantimonate is K 3 BSb 4 O 13 , whose structure features a novel three-dimensional network composed of hexagonal bronze-like 2D (Sb 3 O 9 ) layers that are cross-linked alternatively by edge-sharing Sb 2 O 10 dimers and BO 3 triangles, forming 1D interconnected tunnels running along the a and b directions, which are filled by K + ions.…”

“…11 Unlike metal borophosphates and boroarsenates, little is known about boroantimonates and boroantimonites. 12 The only structurally characterized stoichimetric boroantimonate is K 3 BSb 4 O 13 , whose structure features a novel three-dimensional network composed of hexagonal bronze-like 2D (Sb 3 O 9 ) layers that are cross-linked alternatively by edge-sharing Sb 2 O 10 dimers and BO 3 triangles, forming 1D interconnected tunnels running along the a and b directions, which are filled by K + ions. It is believed that many new boroantimonates can be obtained by replacing K + with other alkali or alkaline earth metal ions and changing B/Sb molar ratios, as well as other reaction conditions.…”

An Unprecedented Antimony(III) Borate with Strong Linear and Nonlinear Optical Responses

“…As early as 1999, Gopalakrishnan and co‐authors reported the first antimony borate RbSbOB 2 O 5 . Subsequently, scientists synthesized a series of antimony borates by high‐temperature reactions in open system, such as K 3 Sb 4 BO 13 , KSbB 2 O 6 , BaSb 2 B 4 O 12 , KSbOB 2 O 5 , and β‐RbSbB 2 O 6 , A 2 SbB 3 O 8 (A=Na, K, Rb), and LnBSb 2 O 8 (Ln=Sm, Eu, Gd, Tb) . Our group also made continuous investigations on the Sb−B−O system and reported a new antimony borate K 2 SbB 3 O 8 in 2016 .…”
