Si-O and P-O motifs in inorganic rings and clusters

This article presents a brief overview of different kinds of silanols and t he important reactions of N-bonded silanetriols. The synthesis and characte rization of silanediols containing Si-N and Si-C bonds, (2,4,6-Me3C6H2)N(Si Me3)Si(Me)(OH)(2) (1e) is described. 1e shows a polymeric crinkled tape typ e of structure due to extensive intermolecular hydrogen bonding. We also de scribe the formation of a neutral copper(II) complex derived from the react ion of CuCl2 with (O)P(3,5-Me(2)Pz)(3) where the ligand undergoes a facile P-N bond cleavage and functions as an N2O type of tridentate ligand.
