摘要：

On reaction of [Y(OCH2CH2OMe)3]10(2) with [(thd)Cu(OCH2CH2OMe)]4 (1a) and [(hfd)Cu(OCH2CH2OMe)]4 (1b) (thd = 2,2,6,6-tetramethyl-3,5-heptanedione; hfd = 1,1,1,5,5,5-hexafluoroacetylacetone), the mixed-metal clusters (thd)4Cu3Y(OCH2CH2OMe)5 (3), [(hfd)2CUY(OCH2CH2OMe)3]2 (4), and (hfd)2(thd)2Cu2Y(OCH2CH2OMe)3 (5) are formed. Their elemental analyses and IR and vis spectroscopic data are reported. 3-5 were studied by X-ray diffractive methods: 3, space group Cc, a = 33.084(5) angstrom, b = 13.980(2) angstrom, c = 18.789(3) angstrom, Z = 4, R = 0.086, R(w) = 0.056 for 6263 reflections with F > 8sigma(F); 4, space group P2(1)/n, a = 10.800(4) angstrom, b = 20.067(7) angstrom, c = 13.703(5) angstrom, Z = 2, R = 0.078, R(w) = 0.072 for 2609 reflections with F > 10sigma(F); 5, space group P1BAR, a = 14.179(4) angstrom, b = 14.425(4) angstrom, c = 14.489(4) angstrom, Z = 2, R = 0.088, R(w) = 0.073 for 7509 reflections with F > 4sigma(F).
