Structure of the silazane (Me3SiN)3(SiMe2)3.[1]

A silazane is a family of compounds with Si-N bonds. Usually the Si and N have organic substituents. They are analogous to siloxanes, with -NR- (R = alkyl, aryl) replacing -O-.[2]

Examples

One illustrative family of silazanes are derived from tert-butylamine, including (CH3)3SiN(H)tBu and (CH3)2Si(N(H)tBu)2.

More structurally complex is [CH3SiN(H)tBu]2(μ-N(H)tBu)2 with bridging amides.[3]

Reactions

The majority of silazanes are moisture sensitive.[4] With water they convert to silanols or siloxanes.
