    Description / Table of Contents: Strontium and Barium Bis[N,N′-bis(trimethylsilyl)benzamidinates] from the Addition Reaction of the Alkaline Earth Metal Bis[bis(trimethylsilyl)amides] and BenzonitrileThe reaction of strontium bis[bis trimethylsilyl)amide] with benzonitrile yields strontium bis[N,N′- bis(trimethylsilyl)benzamidinate] · 2THF, which crystallizes in the orthorhombic space group Pbcn (a = 1845.4(3); b = 131 1,3(2); c = 1838,(3) pm; Z = 4). During the similar reaction of barium bis[bis(trimethylsilyl)amide] with benzonitrile the benzonitrile adduct barium bis[N,N′-bis(trimethylsilyl)benzamidinate] · 2 THF · benzonitrile is formed. After the addition of diphenylacetylene to the strontium di(benzamidinate) in diglyme a clathrate of the composition strontium bis[N,N′-bis(trimethylsilyl)benzamidinate] · diglyme · diphenylacetylene could be isolated; the spectroscopic data as well as the X-ray structure (monoclinic, C2/c, a = 1492.2(2); b = 1539.1(2); c = 2337.8(3)pm; Z = 4) confirm the isolated appearance of the acetylene molecule without interaction to the metal center in solution and in the solid state, respectively.
    Notes: Bei der Umsetzung des Strontiumbis[bis(trimethylsilyl)amids] mit Benzonitril in THF bildet sich Stronitium-bis[N,N′-bis(trimethylsilyl)benzamidinat] · 2THF, das in der orthorhombischen Raumgruppe Pbcn mit {a = 1 845,4(3); b = 1311,4(2); c = 1838,8(3) pm, Z = 4} kristallisiert. Die entsprechende Reaktion des Barium-bis[bis(trimethylsilyl)amids] mit Benzonitril ergibt das Benzonitril-Addukt Barium bis[N,N′ -bis(trimethylsilyl)benzamidinat] · 2 THF · Benzonitril. Nach der versuchsweisen Umsetzung des Strontium-di(benzamidinats) mit Diphenylacetylen in Diglyme läßt sich ein Clathrat der Zusammensetzung Strontiumbis[N,N′-bis(trimethylsilyl)benzamidinat] · Diglyme · Diphenylacetylen erhalten, dessen spektroskopische und strukturanalytische Untersuchungen (monoklin, C2/c, a = 1492,2(2); b = 1539,1(2); c = 2337,8(3) pm; β = 100,74(1)°; Z = 4) das Vorliegen eines unkomplexierten Diphenylacetylen-Moleküls sowohl in Lösung als auch im Festkörper bestätigen.
