Darstellung und Struktur von Na₄SnS₄ ‐ 14 H₂O

Abstract

Natriumorthothiostannat Na4SnS4 · 14 H2O wurde aus wäßriger Lösung rein dargestellt und durch eine vollständige Röntgenstrukturanalyse charakterisiert. Es liegt tetraedrisch koordiniertes Sn in Form isolierter SnS 44−‐Ionen vor (SnS 2,375–2,384 Å). Im Gegensatz zu früheren Annahmen ist also in festen wasserhaltigen Thiostannaten oktaedrische 6‐Koordination als instabil anzusehen. Das Salz kristallisiert monoklin (C2/c) mit a = 8,622, b = 23,534, c = 11,347 Å, β = 110,53°, dexp = 1,81, drönt = 1,821 g · cm−3, Z = 4. Das umfangreiche Wasserstoffbrückensystem wurde vollständig analysiert.

Synthesis and Structures of New Polynuclear Tin Chalcogen Compounds

“…As expected, the endocydic Sn-S bond lengths (246.8(1)-248.7(1) pm) are comparable with the corresponding values in 3, whereas the exocyclic Sn-S bonds are much shorter (234.6(1) and 237.9(1) pm). Similar terminal Sn-S distances have been observed in thiostannates like [SnS 4 ] 4 "[10] or [PhSnS 3 ] 5 '[11].…”

“…1 crystallizes in the space group P2 1 /n with a ϭ 1343.4(3) pm, b ϭ 1134.5 (2) pm, c ϭ 2353.0(7) pm, β ϭ 98.04(3)°(at 220 K). Na 3 [PhSnS 3 ] which is available by the cleavage of Ph 4 Sn 4 S 6 with Na 2 S in aqueous THF reacts with the copper(I) complex [(PhPMe 2 )bipyCuCl] to give the hexanuclear copper(I) compound [(PhSnS 3 ) 2 (CuPPhMe 2 ) 6 ] (1).…”

Syntheses, Structures and Reactivity of Novel Hydrates of ortho‐Sulfidostannte Salts

“…Although the hydrate of the tetrasodium-ortho-thiostannate has already been known for 35 years [1], its heavier alkali metal homologues or respective alkaline earth metal salts have not been reported so far. This might be due to the fact, that the preparation of the sodium salts is easily performed by combining Na 2 S and SnS 2 [1] or SnCl 4 [2] in water, whereas the heavier homologues are to be synthesized on different synthesis routes due to the higher reactivity of A 2 S or AES (A(E) ϭ alkali(ne earth) metal) with water.…”
