Transition Metal Complexes with Linkage to the Thiostannate Units Forced by Suitable Amine Molecules

Abstract

Using the solvothermal approach five new tin-sulfur compounds were synthesized. All compounds exhibit a direct covalent bond between the thiostannate unit and the charge compensating transition metal TM 2+ ion, leading to the formation of discrete neutral molecules, chains or layered structures. In the structures, the [Sn 2 S 6 ] 4anion is connected to the TM 2+ cations in three different ways: (a) only two and opposite terminal S atoms are involved in bonding; (b) the four terminal S atoms connect two different complexes, and (c) the four terminal S atoms link four complexes. The compounds are:

New Transition Metal Oxo‐Thiostannate: Synthesis, Characterization, and Investigation of its Photocatalytic Properties

“…The octahedra NiN 4 S 2 and NiN 4 (OH) 2 (Figure ) are distorted as evidenced by the angles around the Ni 2+ cations (Table S6, Supporting Information). These values are in good agreement with those reported in literature . The distortion of NiN 4 S 2 and NiN 4 (OH) 2 can be quantified using two parameters: the octahedral angle variance σ θ <oct> 2 and the mean octahedral quadratic elongation λ oct .…”

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

“…Dependent on the nature of the cation, networks of different dimensionality are formed, in which the anionic species are linked directly by the metal cations or via intermolecular hydrogen bonding, which is especially the case for organic cations. If charge balance is achieved by metal complexes it depends on the nature of the coordinating ligand whether isolated anions are observed or if thiostannate anions are linked to the metal centres forming structures of different dimensionality …”

Crystal Structures and Selected Properties of CoII Containing Thiostannates prepared by a New Room Temperature Route

“…To simplify the syntheses of thiostannates, we developed a new room temperature synthetic procedures using e.g. {[Ni(tren)] 2 [Sn 2 S 6 ]} n [tren = tris(2‐aminoethyl)amine] or Na 4 SnS 4 · 14H 2 O . Interestingly, all products of the reactions with Na 4 SnS 4 · 14H 2 O contain the [Sn 2 S 6 ] 4– anion, which is obviously in‐situ formed by hydrolysis and condensation reactions.…”
