Abstract
IN solution most of the titanium orthoesters have been shown to be associated into trimers1–3, and a structure has been proposed for the trimeric aggregate1. There has been considerable interest in the structure of this aggregate3–5. In 1963 Ibers6 reported a preliminary crystal structure of tetraethyl titanate showing this to be tetrameric, not trimeric, in the solid state. We have now determined the main features of monomethyltriethyl titanate and have found it also to be tetrameric in the solid state. However, large thermal motion and the limited amount of data for the large number of parameters in the cell have prevented our locating all the carbon atoms or obtaining precise bond distances and angles. Low-temperature data are now being collected to complete the structure determination.
