Synthesis, structure and physicochemical characterization of a noncentrosymmetric, quaternary thiostannate: EuCu2SnS4

Synthesis, Crystal Structure, and Thermal Properties of Na5[SnS4]Cl·13H2O

“…The S–Sn–S angles range from 108.80(2) to 113.16(3)°, indicating that the tetrahedron is slightly distorted. This is in agreement with the values for the tetrahedral angle variance σ θ ‹tet› 2 of 4.0014 and the mean quadratic elongation value (λ tet = 1.0010) calculated using the method suggested by Robinson et al We note that a moderate to strong distortion of the [SnS 4 ] 4– is often observed , , and that the degree of distortion depends on the binding mode of the anion and crystal packing effects.…”

Sn2SiS4, synthesis, structure, optical and electronic properties

“…Recently, metal chalcogenides containing the group 14 elements, in particular the Sn metal, have received increasing interest [1][2][3][4][5][6][7][8][9][10][11]. Sn atom can be stabilized at both the +2 oxidation state with an electron lone pair and the +4 oxidation states without the lone pair electrons in chalcogenides.…”

“…As a result of extensive exploration, many new Sn-containing metal chalcogenides have been discovered, including Ln 2 SnS 5 (Ln = Pr, Nd, Gd and Tb) [2], Ag 6 SnS 4 Br 2 [3], Li 2 CdSnS 4 [4], EuCu 2 SnS [4], Ba 7 Sn 5 S 15 [5], BaSn 2 S 5 [5], Ba 6 Sn 7 S 20 [5], In 4 Pb x Sn y Se 3 [6], Ba 6 Sn 6 Se 13 [7] and SnGa 4 Q 7 (Q = S, Se) [8]. Among them, In 4 Pb x Sn y Se 3 is a promising mid-temperature thermoelectric material candidate [6]; Ba 7 Sn 5 S 15 demonstrates the coexistence of Sn 2 S 3 trigonal-bipyramids and SnS 4 tetrahedra and shows a strong SHG effect [5]; Ba 6 Sn 6 Se 13 has mixed valent Sn 2+ and Sn 4+ cations in 3-fold, 4-fold, and 5-fold coordination environments respectively and shows a moderate NLO effect [7].…”

Hydrogen-bonded co-crystal structure of benzoic acid and zwitterionicL-proline

“…Non-centrosymmetric materials are of particular importance in the field of materials chemistry for the large number of symmetry-dependent properties they can possess, including circular dichroism, pyroelectricity, and non-linear optical behavior (Halasyamani & Poeppelmeier, 1998;McMillen et al, 2012;Aitken et al, 2009). While purposefully engineering these materials can be difficult, one method for eliminating centrosymmetry in crystalline materials is co-crystallization with an enantiopure chiral compound (Kwon et al, 2006).…”
