Synthesis, Crystal Structure, and Optical Properties of a Three-Dimensional Quaternary Hg–In–S–Cl Chalcohalide: Hg₇InS₆Cl₅

Abstract

A crystalline three-dimensional (3D) quaternary chalcohalide, Hg(7)InS(6)Cl(5) (1), has been synthesized through a solid-state reaction under medium temperature. It is the first example in the family of the Hg-IIIA-Q-X (Q = S, Se, Te; X = F, Cl, Br, I) systems. Compound 1 features a 3D network and has an optical band gap of 2.54 eV.

Synthesis, crystal structure and optical property of a novel metal chalcohalide: ZnHg3Se2Cl4

“…Among them, ternary or quaternary metal chalcohalides are hybrid materials, whose compositions and band gaps usually lie between those of binary chalcogenides and binary halides, providing them much richer structural features and more chances to tune their band gaps [16][17][18][19][20][21][22][23][24][25][26][27][28]. In particular, mercury (II)-related chalcohalides are much attractive because mercury ions usually possess diverse coordination geometries varying from linear to octahedral, thus it has a greater tendency to form all kinds of architectures covering 0D, 1D, 2D, and 3D topologies [16,17,[20][21][22][23][24][25][26][27].…”

“…The compound ZnHg 3 S 2 Cl 4 is a case of 2D layered network, in which Hg 6 S 3 Cl 3 forms a novel 12-membered ring, and these rings connected with each other by sharing the edges to form a layer structure [25]. The compounds Hg 2 PbI 2 S 2 [20], Hg 7 InS 6 Cl 5 [16], and TlHg 6 Q 4 Br 5 (Q=S, Se) [27], are four cases of different 3D frameworks.…”

Surfactant-thermal method to prepare two novel two-dimensional Mn–Sb–S compounds for photocatalytic applications

“…[13][14][15][16][17] Several traditional methods including high-temperature solid-state reaction, solution synthesis, and solvo(hydro)thermal method, have been used to prepare crystalline chalcogenides. [18][19][20][21][22][23][24][25] Recently, surfactant-thermal method [13][14][15][16][17][26][27][28] has been demonstrated as a promising strategy to prepare novel crystalline chalcogenides [29] since surfactants possess several charming factors such as the cheaper price, multifunctional properties, and the ability to control the pore sizes and phases of mesoporous frameworks. Our recent results have already shown that the synthesis through surfactant media can produce novel crystalline chalcogenides with diverse structures and interesting properties [26].…”

Partial Geometric Frustration in Inorganic Supramolecular Spin Systems with One-Dimensional Trigonally Aligned Magnetic Chains ∞1(MCl4)2− (M = Fe2+, Co2+)

“…They are widely used as IR detectors, LED’s and switches8. The 3-D diamond-type structures of HgQ can be flexibly truncated by dimension reduction agents9, of chlorides of metals like In, Bi, Cu, Ag, Zr, Hf and so on, to form diverse 3-D mixed structures1011, 2-D layers121314, and 1-D bands15, supporting the opportunities to obtain low-dimensional systems, especially the single-chain and single-molecular magnetic chalcohalides. For the 2-D HgQ layers with hexagonal honeycomb voids, geometric spin frustration can be easily formed if these voids are filled with antiferromagnetically coupled subunits.…”
