- Аннотация: The title complex, [Lu2(C17H28O4P)6]2C7H16, was formed in the reaction between potassium 2,6-di-tert-butyl-4-methylphenyl ethyl phosphate,[K(2,6-tBu2-4-MeC6H2-O)(EtO)PO2], and LuCl3(H2O)6 in water, followed by vacuum drying and recrystallization from heptane. Its crystal structure has triclinic (P1) symmetry at 120 K. The lutetium tris(phosphate) complex has a binuclear [Lu2(-OPO)4] core and the organophosphate ligand exhibits 2O,O0 terminal and 2-1O:1O0 bridging coordination modes with the LuIII ion being sixfold coordinated. The complex is of interest as a precatalyst in the acrylonitrile polymerization process and displays good catalytic activity under mild conditions.
