 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.

 Title    Synthese und Kristallstruktur von CuLn2[B20 5]2 (Ln = Er3*, Lu3+): zwei Kupferlanthanoidborate m it^ [B 20 5 ]4_-A nionen Synthesis and Crystal Structure of CuLn2[B20 5]2 (Ln = E r3+, Lu3+): Two Copper Lanthanoid B orates with 2.[B20 5]4~-Anions  
 Abstract    Single crystals of the new com pounds CuLn2[B20 5]2 (Ln = Er3+(I), Lu3+(II)) were ob­ tained by a B9O 3 flux-technique. They crystallize in the space group C ih -P 2 \lc with I: a = 453.14(6); b = 721.94(5); c = 929.5(4) pm; ß = 90.01(3)°; Z = 2 und II: a = 451.4(4); b = 718.3(1); c = 928.1(3) pm; ß = 90.00(6)°; Z = 2. The compounds are isotypic to CuTm2[B20 5 ] 2 as well as to the mineral Gadolinite (FeY 2 [B eSi0 5 ]2) and exhibit layer like 2.[B20 5]4 --anions consisting of edge sharing B 0 4 -tetrahedra, which form four-and eight-membered rings. The borate anions are separated by layers of elongated C u 0 6-octahedra and slightly distorted tetragonal L n 0 8-antiprisms.
