To determine the structure of the SiCl4 complex with tetramethylurea, its possible structures of composition 1 : 1 and 1 : 2 have been calculated by the RHF, B3LYP, and МР2 methods with the 6-31G(d) basis set. It has been demonstrated that this complex has the 1 : 1 complex and a trigonal-bipyramidal structure with an uncommon equatorial rather than axial location. The formation of the complex is...
