<jats:title>Abstract</jats:title><jats:p> β-NaSbS<jats:sub>2</jats:sub> crystallizes monoclinically, C2/m, with a = 1284(2) pm, b = 582.5(8) pm, c = 581.3(3) pm, β - 118.74(7)°. In the structure there are ψ-SbS<jats:sub>5</jats:sub>-octahedra, which are connected by common edges to sheets separated by the Na ions.</jats:p>

Synthesis of a Novel Two-Dimensional Antimony Sulfide, [C4H10N]2[Sb8S13]·0.15H2O, and Its Structure Solution Using Synchrotron/Imaging Plate Data

“…Amines and elemental sulfur, when combined in water, tend to produce thiosulfate . In contrast, HCO 3 - and HS - have been used as optimum mineralizers for thioantimonates in previous hydrothermal studies. − …”

“…Recently series of main-group sulfide compounds, for example, thioantimonates, − thiostannates, − and thiogermanates − have been synthesized using hydrothermal techniques. Specifically, the thioantimonates show a remarkable variation of stoichiometries and structures.…”

“…The hydrothermal syntheses of thioantimonates gives rise to a variety of chain, − ,, layer, − and three-dimensional 1,12,14 structures; the dimensionality being determined by the presence of Sb−S bonds along 1-, 2-, or 3-noncollinear directions. Distances shorter than the sum of the corresponding van der Waals radii are used to define bonds.…”

“…Distances shorter than the sum of the corresponding van der Waals radii are used to define bonds. Most of thioantimonates are produced in the presence of alkali or alkaline earth metals, ,,− ,− while there a few examples of materials crystallizing from slurries containing organic molecules such as aliphatic or aromatic amines. ,− , Systematic exploratory synthesis employing organic templates in other main-group sulfides have led to a number of novel crystalline compounds, which show structural relationships between the frameworks and the templating molecules. − The geometry of the template within the crystalline structure formed from hydrothermal treatment provides valuable information about possible templating mechanisms.…”

Synthesis, crystal structures, and optical properties of NaCdPnS3 (Pn=As, Sb)

“…EDX analyses performed on freshly cleaved faces of several crystals indicated the presence of all four elements (Na, Cd, As (Sb), S) and for all crystals the average compositions are Na1.1CdAs1.0S3.0 and Na1.2CdSb1.1S3.2. Attempts to replace cadmium with zinc resulted in mixtures of binary and ternary compounds, namely ZnS, NaPnS2 (Pn = As, Sb) [5,38,39]. …”
