Synthesis and structural characterisation of neutral pentacoordinate silicon(iv) complexes with a tridentate dianionic N,N,S chelate ligand†
Abstract
A series of novel neutral pentacoordinate silicon(IV) complexes with SiClSN2C, SiBrSN2C, SiSN3C, SiSON2C, SiS2N2C, SiSeSN2C and SiTeSN2C skeletons (compounds 1–12) was synthesised, starting from PhSiCl3, PhSiBr3, PhSi(NCO)3, MeSiCl3 or C6F5SiCl3. Compounds 1–12 contain (i) a tridentate dianionic N,N,S chelate
