摘要：

Barium bis[N,N'-bis(trimethylsilyl)benzamidinate] . thf . dme crystallizes in the monoclinic space group P2(1)/n with a = 1122.0(2), b = 2190.7(4), c = 1840.2(3) pm, beta = 98.04(1)-degrees and Z = 4 containing a metal center in a distorted monocapped trigonal prismatic surrounding. The barium dibenzamidinate moiety is bent with an angle of 120-degrees, although this leads to different Ba-N distances of 273 and 282 pm originating from the interligand repulsion of the trimethylsilyl groups and the dme substituent. The 1,3-diazaallyl fragment with C-N bond lengths of 132 pm shows a delocalisation of the anionic charge.
