An increasing number of interesting five- and six-coordinate hypervalent silicon complexes are being reported in the chemical literature. Many of these compounds have remarkable or unexpected chemical properties. As part of a larger study of the catalytic chemistry of transition metal-tridentate ketoimine chelates, we present the results of using the metalloid silicon in place of a traditional transition metal in the synthesis of a new range of hyper-coordinate silicon complexes. The complexes are formed by the reaction of tridentate ketoimines with sodium hexamethyl silazide followed by silicon tetrachloride. The resulting unusual six-coordinate silicon complexes were characterized with <sup>1</sup>H and <sup>13</sup>C NMR. The electronic properties of the fluorescent complexes were investigated with absorbance and fluorescence spectroscopies.
