摘要：

The reaction of bis[bis(trimethylsilyl)methyl]zinc with 2,2'-bipyridine yields 2,2-bipyridyl-bis[bis(trimethylsilyl)methyl]zinc which crystallizes from cyclo-pentane in the monoclinic space group P2(1)/c with a 888.4(3), b 1612.9(5), c 2175.7(6) pm, beta-101.07(1)-degrees; Z = 4. The zinc atom is surrounded by the two nitrogen donors of the 2,2'-bipyridyl ligand in a distorted tetrahedral fashion and both the alkyl groups with Zn-N and Zn-C bond distances of approximately 219 and 203 pm, respectively. Owing to the short N ... N distance (bite) of 264 pm a small NZnN angle of only 74.1-degrees is observed, on the other hand, the CZnC angle is with a value of 126.4-degree remarkably large.
