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-.<ref>{{cite book |chapter-url=https://goldbook.iupac.org/terms/view/S05669|chapter=Silazanes|doi=10.1351/goldbook.S05669 |title=The IUPAC Compendium of Chemical Terminology |date=2014 }}</ref>
==Examples== One illustrative family of silazanes are derived from tert-butylamine, including (CH<sub>3</sub>)<sub>3</sub>SiN(H)tBu and (CH<sub>3</sub>)<sub>2</sub>Si(N(H)tBu)<sub>2</sub>.
More structurally complex is [CH<sub>3</sub>SiN(H)tBu]<sub>2</sub>(μ-N(H)tBu)<sub>2</sub> with bridging amides.<ref>{{cite journal |doi=10.1021/cr00099a001 |title=Cage compounds with main-group metals |date=1990 |last1=Veith |first1=Michael |journal=Chemical Reviews |volume=90 |pages=3–16 }}</ref>
There are a wide variety of polysilazanes.
==Reactions== The majority of silazanes are moisture sensitive.<ref>{{Cite book|url=https://books.google.com/books?id=BkPBtgAACAAJ|title=Silazane Precursors to Silicon Nitride|date=1984|publisher=Defense Technical Information Center|language=en}}</ref> With water they convert to silanols or siloxanes.
