Sys. Wang et al., A CHELATE-STABILIZED TUNGSTEN-IMIDO-MONOALKYL COMPLEX, [WCL(PHN)(CH2CME3)(O-C6H4(NSIME3)(2))], Acta crystallographica. Section C, Crystal structure communications, 53, 1997, pp. 436-438
The title compound, CN,N'-bis(trimethylsilyl)-o-phenylenediamido-N,N']
(chloro)(neopentyl)(phenylimido-N)tungsten(VI), [WC1(C5H11)(C6H5N)(C1
2H22N2Si2)], has been synthesized and its crystal structure determined
. The geometry around the W atom, imposed by the bidentate o-phenylene
diamido ligand and the bulky neopentyl ligand, is that of a distorted
trigonal bipyramid. A relatively short W-N(imido) bond length of 1.741
(4) Angstrom is interpreted as arising from the interaction of the lon
e pair of electrons on the imido N atom and the tungsten metal center.
