description

The first isolation of an antimony(III) thiocyanate complex salt, [(CH3)4N][Sb(CNS)4] (I), and of two adducts of the Sb(CNS)3 formal unit with potentially tridentate nitrogen donors, Sb(CNS)3tpta (II) and [Sb(CNS)3]3(dqp)2 (III), is described. In these derivatives, infrared and Mossbauer spectral data are essentially indicating the predominant presence of N-bonded thiocyanate. For complex I, the occurrence also of groups bridging through the nitrogen atom is advanced. Synthese, IR- und 121Sb-Mosbauer-Spektren von Antimon (III)-thiocyanat-Komplexen Die erstmalige Darstellung eines Antimon(III)-thiocyanat-Komplexes, [(CH3)4N][Sb(CNS)4] (I) und von zwei Addukten der formalen Sb(CNS)3-Einheit mit potentiell dreizahnigen Stickstoffdonatoren, Sb(CNS)3tpta (II) und [Sb(CNS)3]3(dqp)2 (III) wird beschrieben. Die IR- und Mosbauer-Daten zeigen bevorzugtes Vorliegen von N-gebundenem Thiocyanat. Fur Komplex I werden auch uber Stickstoff verbruckte Gruppen gefunden.
