Na2GaS2Cl: A new sodium-rich chalcohalide with two-dimensional [GaS2]∞layers and wide interlayer space

By introducing halogens to the A/Ga/Q (A = Na, K; Q = S, Se) system, one new chalcohalide namely Na2GaS2Cl was successfully obtained. It crystallizes in the orthorhombic space group Cmcm (63). Na2GaS2Cl has a layered structure consisting of two dimensional [GaS2]∞ layers which are stacked in face to face and back to back arrays and separated by Na+ and Cl- ions. Interestingly, supertetrahedral building units [Ga4S10] (T2) which are rarely found in metal chalcogenides and metal chalcohalides are formed in this structure. Moreover, the distances of two adjacent layers are around four times larger than the ionic radius of the Na+ ion, which is very likely to provide a perfect environment for the storage and migration of Na+ ions. In particular, the volume concentration of the Na+ cations in this compound is as high as 1.54 × 1022 cm-3. The UV-vis-NIR spectroscopy measurement reveals that the optical band gap of this title compound is 3.06 eV. The electronic structural calculations on Na2GaS2Cl show that the band gap is mainly determined by the [GaS4] groups and Na-Cl ionic bonding.

Direct preparation of anhydrous sodium oligosulfides from metal sodium and elemental sulfur in aprotic organic media directed toward synthesis of silane coupling agent

Anhydrous sodium oligosulfide was prepared by the heterogeneous reaction of metal sodium and elemental sulfur in aprotic solvents. The oligosulfide consisted of a mixture of several Na2Sn (n = 2 - 8). Organic oligosulfides (R2Sn, n ≥ 2) including moisture-sensitive one were synthesized by the reaction with organic halides in high yeilds under mild conditions.
