The title complex, [Lu 2 (C 17 H 28 O 4 P) 6 ]·2C 7 H 16 , was formed in the reaction between potassium 2,6-di- tert -butyl-4-methyl-phenyl ethyl phosphate, [K(2,6- t Bu 2 -4-MeC 6 H 2 -O)(EtO)PO 2 ], and LuCl 3 (H 2 O) 6 in water, followed by vacuum drying and recrystallization from heptane. Its crystal structure has triclinic ( P [Formula: see text]) symmetry at 120 K. The lutetium tris-(phosphate) complex has a binuclear [Lu 2 (μ-OPO) 4 ] core and the organophosphate ligand exhibits κ 2 O , O ' terminal and μ 2 -κ 1 O :κ 1 O ' bridging coordination modes with the Lu III ion being sixfold coordinated. The complex is of inter-est as a precatalyst in the acrylo-nitrile polymerization process and displays good catalytic activity under mild conditions. |
