8배위 이트륨(III) 화합물 Y(tpb)3(H2O)2을 합성하였고 X-선 회절법으로 구조를 규명하였다. 이 화합물은 12 면체의 구조를 가지며, 두 면(Y-O2-O1-O5-O6 and Y-O4-O3-O8-O7)사이의 각은 89.59o이다. 또한, O1-O5과 O3-O8 의 거리는 2.965 and 2.995 A이며 O2-O6과 and O4-O7의 거리는 4.256 and 4.403 A이다.

The eight coordinated yttrium(III) complex Y(tpb)3(H2O)2 (Htpb=4,4,4-Trifluoro-1-phenyl-1,3-butanedione) has been synthesized and structurally characterized by X-ray diffraction method. The coordination polyhedron of Y(tpb)3(H2O)2 has a dodecahedron. The angle between two trapezia, Y-O2-O1-O5-O6 and Y-O4-O3-O8-O7, is 89.59°. The O1-O5 and O3-O8 distances are 2.965 and 2.995 A whereas the O2-O6 and O4-O7 distances are 4.256 and 4.403 A.
