ChemInform Abstract: On the Flexibility of Thioantimonate Networks: Solvothermal Syntheses and Crystal Structures of Six New Thioantimonates(III) with the [Sb₄S₇]^2‐ Anion.

Abstract

The structures of the new thioantimonates (III) (monoclinic, space group P21/c, Z = 4), (VI) (monoclinic, P21/n, Z = 4), and (VIII) (triclinic, P1, Z = 2) are determined by single crystal XRD. Compounds (III) consists of anioniclayers characterized by Sb8S8 rings. The [M 1 (dien)2] 2+ units are located above and below the pores of the rings. Despite the larger size of the cation complex the network topology of (VI) is similar to that of the (III). The transition metals in the thioantimonates (VIII) are fivefold coordinated by four N atoms of the amine molecule and one S atom of the thioantimonate anion forming a MN4S trigonal bipyramid. Sb8S16 building blocks are the central structural motifs of the anion. Several short S···H distances in all compounds indicate hydrogen bonding interactions. -(LUEHMANN, H.; REJAI, Z.; MOELLER, K.; LEISNER, P.; ORDOLFF, M.-E.; NAETHER, C.; BENSCH

Syntheses, crystal structure, and photoelectric properties of two Zn-based chalcogenidoantimonates Zn–Sb–Q (Q = S, Se)

“…2 2)). 31 Further analysis revealed a tendency for Zn to assume a 5-coordination in organic-decorated antimony chalcogenides, a trait manifested in the coordination mode of compound 1 and similarly observed in the structures of [Zn(trien)]Sb 4 S 7 22 and…”

“…These bond lengths and angles are similar to reports in the literature, such as [Mn(C 4 H 13 N 3 ) 2 ] n [CoSb 2 Se 5 ] n (Sb-Se:2.5524(7)-2.6544(7) Å); Sb-Se-Se: (96.60(2)1-102. 30(2)1), 28 [Zn(trien)]Sb 4 S 7 : N-Zn-N: (79.83(17)-117.07(16) Å) 22 and [Zn(tren)] 4 (In 2 As 2 S 8 ) 2 : (Zn-N: 2.073(5)1-2.312(5)1). 29 Compound 2 crystallizes in the tetragonal crystal system in space group space group of I4 1 /a, also shown as a zerodimensional cluster structure.…”

“…Employing chelating amines as ligands facilitates the formation of inorganic-organic hybrid antimony compounds featuring an abundance of TM 2+ groups (TM = Cr, Mn, Fe, Co, Ni, Zn). These compounds typically create diverse low-dimensional structures through the formation of unsaturated [TM(amine) x ] n+ as equilibrium cation, which then binds to the anionic framework via covalent TM-Q interactions, 16,17 such as [Cr(C 6 H 18 N 4 )(SbS 3 )], 18 20 [TM(tren)][InSbSe 3 S] (TM = Co, Ni), 21 [Zn(trien)]Sb 4 S 7 , 22 etc. This strategy enhances structural diversity and integrates the electronic, magnetic, and optical properties of TM ions with inorganic frameworks.…”
