The neutral pentacoordinate silicon(IV) complex 10 ( Si ON 3 C skeleton) and the neutral hexacoordinate silicon(IV) complex 11 ( Si ON 4 C skeleton) were synthesized, starting from methyldi(thiocyanato‐ N )silane ( 7 ). In addition to their monodentate thiocyanato‐ N and methyl ligands, these compounds contain a tridentate dianionic O , N , N ligand ( 10 ) or a tridentate monoanionic O , N , N ligand ( 11 ). Compounds 10 and 11 were characterized by single‐crystal X‐ray diffraction and solid‐state and solution NMR spectroscopy. According to these studies, compounds 10 and 11 exist in solution as well.
