Hexamethyldisilazane(HMDZ)
Hexamethyldisilazane(HMDZ) is an organosilicon compound with the molecular formula [(CH3)3Si]2NH. The molecule is a derivative of ammonia with trimethylsilylgroups in place of two hydrogen atoms. An electron diffraction study shows that silicon-nitrogen bond length (173.5 pm) and Si-N-Si bond angle (125.5 ) to be similar to disilazane (in which methyl groups are replaced by hydrogen atoms
