Synthesis and structure of 1,3-bis(hydroxysilyl)-2,4-dimethyl-2,4-diphenylcyclodisilazane

► 1,3-Bis(hydroxysilyl)-2,4-dimethyl-2,4-diphenylcyclodisilazanes were prepared. ► Structures of 5 and 6 were successfully characterized by IR, NMR, EA and X-ray. ► Mixed phenyl substituents on the Si4N2 skeleton lead to cis/trans isomers for 3.
