【 摘 要 】

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 (P\overline{1}) symmetry at 120 K. The lutetium tris­(phosphate) complex has a binuclear [Lu2(μ-OPO)4] core and the organophosphate ligand exhibits κ2O,O′ terminal and μ2-κ1O:κ1O′ 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.
