 Title    Metall-N,N  
 Abstract    -bis(trimethylsilyl)benzamidinate: Synthese und Kristallstruktur von Bis[N,N-bis(trimethylsilyl)benzamidinato)chroni(II), [P hC (N SiM e3)2l2Cr Metal-N,N'-bis(trimethylsilyl)benzamidinates: Synthesis and Crystal Structure of Bis[N,N'-bis(trimethylsilyl)benzamidinato]chromium(II), [PhC(NSiM e3)2]2Cr The preparation o f N,N'-bis(trimethylsilyl)benzamidinates o f chromium, manganese, zinc and bismuth is described. The chromium(II) derivative [PhC(NSiM e3)2]2Cr (2) has been char­ acterized by an X-ray structure determination. Treatment o f CpTiCl3 with one equivalent o f N a[PhC (N SiM e3),] • 0.5 Et^O yields the mixed Cp/benzamidinate complex [PhC(NSiM e3)2]CpTiCl2 (9).
