 Title    A New Binuclear Lutetium(III) Dimethyl-N-trichloroacetylamidophosphate Complex with a 7 , 7 *-Dipyridyl Bridge, {Lu[CCl3C(0)N P(0)(0C H 3)2]3}2-A x(7,7'-dipy)  
 Abstract    A new type of binuclear coordination compound of lutetium, {Lu2L6 /i-(7 ,7 '-dipy)} (where L = dimethyl-N-trichloroacetylamidophosphate anion and 7 ,7 '-dipy = 4,4'-dipyridyl), has been obtained. The IR spectroscopic data reveal that the ambidentate phosphoryl ligand is coordinated to the metal center in a bidentate manner via the phosphoryl and carbonyl oxygen atoms. The crystal and molecular structure of {LniLö-^-(7 ,7 '-dipy)} has been determined by means of X-ray diffraction (triclinic, space group P i with parameters: a = 9.259(2), b = 12.530(3), c = 16.548(3) A, a = 85.44(3)°, ß = 75.64(3)°, 7 = 70.56(3)°, Z = 1). The structure is made up of centrosymmetric binuclear molecules, in which the neutral heterocyclic ligand is coordinated to the metal centers in a bidentate bridging manner via its nitrogen atoms. The coordination number of each Lu(III) atom is 7 [60(L~) + N((7 ,7 '-dipy)]. Phosphoryl and carbonyl groups of the L~ ligands are disposed in syn-position and are included in the six-membered chelate metallocycles. The coordination polyhedron of lutetium can be described as distorted mono-capped octahedron.
