“…Each Zn(NH 3 )Se 3 unit is bound to three SbSe 3 fragments via three shared corners as well as each SbSe 3 group is surrounded by three Zn(NH 3 2+ cationic complexes and additionally of three molecules of ammonia per formula unit, which do not show any coordination. The polarity of the structure of 4 is based on the in each case concordant orientation of the SbSe 3 pyramids, the [Zn(NH 3 [45] since in their structure metal atoms are covalently bound in polyanionic selenidoantimonate chains. The structure of [Zn(tren)]Sb 4 S 7 [17] contains a pentacoordinate zinc atom bound to thioantimonate chain by one Zn-S bond only.…”

“…In the former ribbon, the alternating connection of two {In3S 4 } tetrahedra and two {Sb2S 3 } trigonal pyramids gives rise to a tetranuclear heterometallic {In 2 Sb 2 S 10 } cluster, which further connects with the neighboring ones by edge-sharing (In3−S7−Sb2). Such an {In 2 Sb 2 S 8 } n ribbon has only been reported in [(Me) 2 NH 2 ] 2 [In 2 Sb 2 S 7 ], 43 55 The {In 2 SbS 8 } clusters arrange along the b axis and share the S3 ions to generate an infinite {In 2 SbS 7 } n ribbon. A pair of such ribbons further merges into a double-ribbon of {In 4 Sb 2 S 12 } n by sharing the common S4 ions.…”

Reported here are the syntheses, structures, and characterizations of four novel In−Sb−S compounds containing organic amines, namely, [PAH] 3 [In 3 Sb 2 S 9 ] (PA = npropylamine) (1), [Fe(en) 3 ][In 2 Sb 2 S 7 ] (en = ethylenediamine) (2), [Mg(dien) 2 ][In 2 Sb 2 S 7 ]·0.5H 2 O (dien = diethylenetriamine) (3), and In 2 (N,N-dmen) 2 Sb 2 S 6 (N,N-dmen = N,N-dimethylethylenediamine) (4). Compound 1 features a [In 3 Sb 2 S 9 ] n 3n− layer assembled by the alternating linkage of the {In 2 Sb 2 S 8 } n ribbons and the {In 4 Sb 2 S 12 } n double-ribbons. Both compounds 2 and 3 possess layered anionic parts with the same stoichiometry of [In 2 Sb 2 S 7 ] n 2n− but distinct linkage modes between the subunits of {In 2 S 7 } groups and Sb 3+ ions. Notably, the {In 2 Sb 2 S 9 } heterometallic cluster observed in 3 is initially regarded as the secondary building unit (SBU) for the construction of the [In 2 Sb 2 S 7 ] n 2n− layer. Compound 4 features a novel discrete inorganic−organic hybrid molecule of In 2 (N,N-dmen) 2 Sb 2 S 6 . Through the structural analyses on 1−4, the organic amines applied played three different roles on the formation of the final crystalline products. For 1, the protonated n-propylamines arrange in the space around the anionic network and balance the negative charge. For 2 and 3, the chelating polyamines coordinate to central metal ions to form metal complexes, which then act as space-filling and charge-balancing agents. For 4, two N,N-dimethylethylenediamines chelate to two In 3+ ions of the inorganic segment through coordination bonds, leading to the formation of a rare inorganic−organic hybrid cluster. At last, we gave a systematic discussion about the characteristics and roles of organic amines in all related In−Sb−S compounds. In one word, the work presented here enriches the structural chemistry of the main-group heterometallic chalcogenidometalates, providing more chances for researchers to work out the rules in their composition− or structure−function relationship.

“…Chalcogenides contain Group 15 elements have been drawing more and more attentions due to their structural diversity [1][2][3][4][5][6], and tremendous potential applications as nonlinear optics [7][8][9], thermoelectric device [10][11][12], ion exchange [13][14][15][16], and photocatalysis [17][18][19]. Thioarsenates(III), a subclass of chalcogenides, typically demonstrate a special structural feature of the stereochemically active 4s 2 lone pair electrons associated with As(III) [1,3].…”
