Über Verbindungen subvalenter Hauptgruppenmetallkationen mit Dithiolaten, 3. Mitteilung [1]. Die Kristallstruktur von [As(C₆H₅)₄]₂[Pb(S₂C=C(CN)₂)₂]/Compounds of Subvalent Main Group Metal Cations with Dithiolates, Part 3 [1] Crystal Structure of [As(C₆H₅)₄]₂[Pb(S₂C=C(CN)₂)₂]

The crystal structure of [AsPh 4 ] 2 [Pb(S 2 C=C(CN) 2 ) 2 ] has been determined by X-ray diffraction. In the pyramidal complex anion [Pb(S 2 C=C(CN) 2 ) 2 ] 2- Pb is coordinated to the sulfur atoms of the dithiolates. The geometry is indicative for a stereochemically active lone-pair at the apex of the square pyramid.
