“…Simulation of mirror charges31 allowed the theoretical treatment of the highly charged molecules. The calculated SnSe distances in the Co/Sn/Se cluster anions tended to be larger than the experimentally observed ones; a comparable situation was found for the results of calculations on the [Sn 4 Se 10 ] 4− ion27 (SnSe t : +4 to +5 pm, Sn(μ 2 ‐Se): +7 to +10 pm with respect to the crystallographically determined values). In contrast, the computed CoSe bond lengths in the ternary anions were all somewhat shorter than the experimental ones, which likewise was in accordance with the results of calculations on the adamantane‐type anion [{Co(SPh)} 4 (μ 2 ‐SPh) 6 ] 2− 32 (CoS: −3 to −4 pm with respect to the crystallographically determined values).…”

“…The SnSe bond lengths in 1 (SnSe t 247.8(2), 249.0(1) pm, Sn(μ 2 ‐Se) 250.9(1)–252.8(1) pm) correspond with those of the adamantane‐type selenostannate( IV ) anion in [2,2,2‐crypt‐K] 4 [Sn 4 Se 10 ]27 (2,2,2‐crypt=4,7,13,16,21,24‐hexaoxa‐1,10‐diazabicyclo[8.8.8]hexacosane). The Co(μ 2 ‐Se) and Co(μ 4 ‐Se) distances are very similar (Co(μ 2 ‐Se) 242.5(2)–244.8(1) pm; Co(μ 4 ‐Se) 243.6(1), 245.0(2) pm).…”

Dedicated to Professor Dieter Fenske on the occasion of his 60th birthdayThe stabilization of binary aggregates of main group elements [E 0x E y ] qÀ in the coordination sphere of transitionmetal ions M nþ (E' or E ¼ Group 13±15 or 16 element), and thus the formation of structures that contain ternary heavy atom frameworks, is an area of increasing research activity. [1±16] Besides diverse range of molecular and crystal structures, the synthesis of some ternary M/E'/E systems that show polymeric anion substructures representing ™open solidstate structures∫, as found in Rb 3 [AgGe 4 Se 10 ]¥2 H 2 O [10] or K 2 [MnSnS 4 ], [11] have recently attracted attention. Such compounds combine both zeolite-type and semiconducting properties. If binary alloys or salts of binary anions are used for the construction of the E'/E aggregates instead of separate components, the investigations additionally serve to study the reaction behavior and stability of these systems in the presence of transition-metal compounds. However, most reports on the latter deal with binary reactants of Groups 15/16, [1, 13±16] for example the synthesis of [PPh 4 ] 2 -[Mn(CO) 3 (As 3 Se 3 ) 5 ] by using [As 4 Se 4 ]. [13b] Only most recently, were some results published that considered the surfactanttemplated solvothermal synthesis of mesoporous solids like (C 16 H 33 NC 5 H 5 ) x [Pt y Sn 0 4 Se 10 ] (x ¼ 1.9±2.8; y ¼ 0.9±1.6).[12] One of our current aims is to generate coordination compounds by reacting binary anions of Groups 14 and 16.

“…The broad asymmetric peak in the range of 325–385 cm −1 observed in SnSe 2 ‐doped samples was associated with the A 1 mode of

{SnS}_{4}^{4 -}

{SnSe}_{4}^{4 -}

{PS}_{4 - z} {Se}_{z}^{3 -}

Dual Doping: An Effective Method to Enhance the Electrochemical Properties of Li₁₀GeP₂S₁₂‐Based Solid Electrolytes

Multiple doping is widely used to improve the performance of a material, including its electrical transport, mechanical, and photovoltaic properties. In this paper, Sn-Se dual-doped Li 10 GeP 2 S 12 (LGPS, thio-LISICON II analogue) electrolytes were synthesized via ball milling and sintering and compared with those Sn or Se single-doped. Successful Sn and/or Se substitution expanded the unit cell and formed SnSe 4À 4 units, which were verified by X-ray powder diffraction, energy-dispersive X-ray spectroscopy, and Raman spectroscopy. In contrast to the limited benefits of Se single doping and the negative effects of Sn single doping, Sn-Se dual doping demonstrated up to 53% enhancement in ionic conductivity. More importantly, Sn-Se dual-doped LGPS showed an extremely low activation energy of 16 kJ/mol, which is one of the lowest known values for lithium ion conductors; as well as one of the widest electrochemical windows of 8 V. Sn-Se dual-doped LGPS is a promising electrolyte for advanced all-solid-state batteries.
