The synthesis and characterisation of two new iron thioantimonates: [Fe(en)3]2Sb2S5·0.55H2O and [Fe(en)3]2Sb4S8

Solvothermal Synthesis and Crystal Structure of the Non‐Centrosymmetric Thioantimonate [Ni(tren)2]2[Ni(tren)(en)]2(Sb4S8)2·0.25H2O

“…[16,65,66] The former anion occurs as a ring constructed by three corner‐sharing SbS 3 pyramids. The latter anion crystallizes either as a short chain65 or as isolated ring anions. [16,66] We note that [SbS 2 ] – chains constructed by corner‐sharing SbS 3 units are also present in Sr 3 Sb 4 S 9 ,67 in [M(en) 3 ]Sb 2 S 4 (M = Co, Ni),68 or in ASbS 2 (A = Rb, Cs) 69.…”

1,4,8,11-Tetraazacyclotetradecane antimony(III) sulfide

“…These may be connected through corner-or edge-sharing to create larger secondary building units, including a variety of Sb x S x hetero-rings and [Sb 3 S 6 ] 3À semicubes. Condensation of these building units can form chain, layered and three-dimensional antimony±sul®de structures, such as [Fe(C 2 H 8 N 2 ) 3 ] 2 [Sb 4 S 8 ] (Lees et al, 2005), [Fe(C 4 H 13 N 3 ) 2 ][Sb 6 S 10 ]Á0.5H 2 O (Stahler et al, 2001) and [Co(C 2 (Vaqueiro, Chippindale et al, 2004), respectively. The synthesis of these materials is generally performed using organic amines as structure-directing agents.…”

Transition‐Metal Linkage of Antimony‐Sulfide Chains in [M(dien)2]{Sb18S30[M(dien)]2} (M = Mn, Fe, Co)

“…These can themselves act as structure directing agents, whilst also fulfilling a charge‐balancing role. For example cationic tris(ethylenediamine) transition‐metal complexes serve to balance the charges of SbS 2 – and Sb 4 S 7 2– infinite chains in [ M (en) 3 ]Sb 2 S 4 ( M = Co, Ni, Fe), and [ M (en) 3 ]Sb 4 S 7 ( M = Co, Ni, Fe),, respectively, whilst [Ni(terpy) 2 ] 2+ (terpy = 2,2′:6′,2′′‐terpyridine) cations fulfil a similar role between Sb 10 S 17 4– layers in [Ni(terpy) 2 ] 2 [Sb 10 S 17 ] . This characteristic extends into the rare examples of three‐dimensional structures, including [Co(en) 3 ]Sb 12 S 19 , in which the three‐dimensional anionic thioantimonate framework contains [Co(en) 3 ] 2+ cations located within one‐dimensional channels and [Ni(aepa) 2 ]Sb 4 S 7 [aepa = N ‐(aminoethyl)‐1,3‐propanediamine], which contains cationic nickel complexes located above and below large Sb 14 S 14 rings …”

“…[4] Thioantimonates (frequently termed "antimony(III) sulfides" in the literature) exhibit a particularly rich structural diversity, and can adopt threefold and pseudo 4-and fivefold coordination. [5][6][7][8] The primary building units are generally SbS 3 3trigonal pyramids, arising from the stereochemical effect of the lone pair of electrons associated with Sb III , which can be linked by vertex or edge-sharing to generate a range of discrete [9] and extended chain, [10] layered, [11] and three-dimensional structures. [12] Recently efforts have focused on exploiting the complementary coordination preferences of different main-group elements to generate novel structures.…”
