The interaction of 5-fluorouracil-1-acetic acid (5FuAA) and its Cu! complex (5FuAACu) with DNA was also investigated by using spectral, viscometric, electrochemical and agarose gel electrophoresis methods. The results of interaction with DNA suggest that both 5FuAA and 5FuAACu can bind to DNA in a static electricity attraction mode. But the attraction of 5FuAACu is greater than that of 5FuAA.展开更多

It is of monoclinic system, space group P21/c with a = 9.213(2), b = 17.479(4), c = 11.510(2) ? b = 100.32(3)o, V = 1823.7(6) 3, Z = 4, C17.5H16Cl2FeHgN2, Dc = 2.119 g/cm3, m = 9.497 mm-1, F(000) = 1100, R = 0.0436 and wR = 0.0987. The independent reflections are 3527, of which 3153 with I ≥ 2s(I) were observed. The compound contains a five-membered metallocycle. The mercury atom is bonded with the 2-position of substituted cyclopentadienyl ring (Cp), and coordinated weakly to the N atom of imino group. The pyridyl ring is almost perpendicular to the substituted Cp which is nearly coplanar with the metallocycle. The Hg(1)C(1) and Hg(1)Cl(1) bond lengths are 2.050(8) and 2.321(2) ? respectively.展开更多
