Abstract:
The magnetic shielding tensor and quadrupole interaction parameters, as well as the mutual orientation of tensors for the (≡SiO)VOCl2 complex obtained by the immobilization of VOCl3 on the SiO2 surface are determined. The state of VOCl3 on the surfaces of MgCl2 and modified SiO2 with all surface OH groups replaced by Cl atoms is studied. To prepare the modified SiO2, CCl4 and SiCl4 are used as chlorinating agents. The formation of structurally similar pentavalent vanadium complexes on the surface of these supports is shown. A model for the coordination environment of vanadium on the chlorine-containing supports is proposed. The vanadium atom exists in the distorted pentahedral environment and is bound to the support through either two chlorine atoms or chlorine and oxygen atoms. A correlation between the coordination of VOCl3 and catalytic properties of VOCl3/MgCl2 is assumed.
