Synthesis, structure and characterization of two new copper(І)-thioarsenates (ІІІ) constructed by the [AsS3]3− and CuS units

Facile surfactant-thermal syntheses and characterization of quaternary copper thioantimonates(III) ACu 2 SbS 3 (A = K, Rb, Cs)

“…Interestingly, CsCu 2 AsS 3 [20] has an anionic layer with the similar stoichiometry to KCu 2 AsS 3 [35] and CsCu 2 SbS 3 , but their structures are totally different. In the structure of CsCu 2 AsS 3 , the [Cu 2 AsS 3 ] À anionic layers are mainly constructed by three different sized rings: 4-membered [CuAsS 2 ] rings, 5-membered [Cu 2 AsS 2 ] rings and 6-membered [Cu 2 AsS 3 ] rings through vertex-sharing of …”

“…It is reported that Cu(I) ion, one of the chalcophilic ions [19], tends to exhibit flexible coordination numbers with sulfur, and highly diversified linkages through vertex or edges [20]. Therefore, the integration of Cu(I) ions is beneficial to generate new multinary thioantimonates(III) with novel crystal structures and integrated physical properties.…”

Strong Photocurrent Response of Selenoarsenates With Different Transition Metal Complexes as Structure-Directing Agents

“…The wide variety of structures and properties of chalcogenidoarsenates have led to great interest in many areas, including semiconductors, photoelectricity, magnetism, ion exchange, and nonlinear optics ( Sheldrick and Wachhold, 1998 ; Zhou et al, 2009 ; Zhang et al, 2012 ; Xiong et al, 2013 ; Yao et al, 2013 ; Liu et al, 2014 ; Zhou et al, 2015 ; Zhou, 2016 ; An et al, 2017 ; Wang et al, 2020 ; Chen et al, 2021 ; Li et al, 2021 ; Liu et al, 2021 ). The chalcogenidoarsenates are formed by corner- or edge-sharing of [AsQ 3 ] 3- and [AsQ 4 ] 3- (Q = S, Se) units, resulting in a variety of chalcogenidoarsenate aggregates.…”

“…So far, some [M x As y Q z ] chalcogenidoarsenates (M = Cu, Ag, Cd, Hg) have been obtained under solvothermal conditions. Such as, two kinds of [Cu 2 AsS 3 ] n − chains (5-membered Cu 2 AsS 2 rings and 6-membered Cu 2 AsS 3 rings) form the two-dimensional anionic [Cu 2 AsS 3 ] n − layer ( Yao et al, 2013 ). The one-dimensional [AgAsS 4 ] n 2n− chain is a result of corner and edge sharing between AgS 4 and AsS 4 .…”

Two Organic Hybrid Manganese Selenoarsenates: The Discovery of One-Dimensional Low-Valent Selenoarsenate(II)

“…Moreover, the inclusion of transition metals (TMs) in the chalcogenoarsenate backbones may result in new classes of multifunctional TM chalcogenoarsenates, because of the combination of distinctive physical properties of the TM and the host chalcogenoarsenates. , The soft Lewis acidic TM ions (such as Cu + , , Ag + , and Hg 2+ ) can bond directly to the soft Lewis basic chalcogen atoms of chalcogenoarsenate units in the presence of chelating organic amines, while other TM ions (such as Mn 2+ , Co 2+ , and Zn 2+ ) are easily chelated by aliphatic chelating amines or chelating π-conjugated ligands to form unsaturated TM complexes as either bridging or decorating groups, which can further bond to the chalcogen atoms of the chalcogenoarsenates, resulting in novel organic hybrid TM chalcogenoarsenates with varied structures that contain TM ions adopting either a trigonal biyramidal (five-coordinate) or an octahedral (six-coordinate) environment; however, no seven-coordinated TM complexes combined with chalcogenoarsenate anions via TM–Q bonds have emerged to date. In this work, we report the solvothermal syntheses, crystal structures, and properties of two new manganese selenoarsenates, [Mn­(en) 3 ]­[MnAs II 2 Se 4 ] ( 1 ) and {[Mn­(atep)] 2 [Mn­(tepa)]­(As V Se 4 ) 2 } ( 2 ).…”
