 Title    Tetrazinn(II)-und Bariumtrizinn(II)-tetrakis[/i3 -tri-ter/-butyIsilylphosphan- diid]-Verbindungen mit einem Tetrametallatetraphosphacuban-Gerüst Tetratin(II) and Barium Tritin(II) Tetrakis[//3-tri-rm-butylsilylphosphandiide] Compounds with a Tetrametallatetraphosphacubane Core  
 Abstract    The metalation o f tri-terr-butylsilylphosphane with bis[bis(trimethylsilyl)amino]stannylen yields nearly quantitatively the tetrameric tin(II) tri-terf-butylsilylphosphandiide with a central Sn4 P4 cubane moiety. Barium bis[tri-/£Tf -butylsilylphosphanide] is accessible via the reaction o f tri-?£T/-butylsilylphosphane with barium bis[bis(trimethylsilyl)amide] in the molar ratio 2 : 1 . This phosphanide reacts with bis[bis(trimethylsilyl)amino]stannylen to give barium tritin(II) tetrakis[/i3-tri-ter?-butylsilylphosphandiide].
