The title complex [Cu3L3(H2O)]DMFH2O (H2L = 4-(3-hydroxy-2-ethyl-4- pyridinone-1-yl)-aniline condensation salicylaldehyde) was obtained. The single-crystal X-ray study shows that it is a trinuclear compound [Cu3(C20H15N2O3)3(H2O)]DMFH2O. The coordi- nation sphere about each copper ion in the complex consists of two oxygen atoms from hydroxylpyridinone moiety of one ligand and one oxygen and one nitrogen atoms from salicyladehyde Schiff-base moiety of another ligand arranged in a slightly distorted square planar geometry. Among the three copper ions, one (Cu(2)) is coordinated by the other oxygen atom of water molecule on the fifth coordinate position to form a distorted square pyramid geometry. The crystal is of monoclinic, space group P21/c with a = 12.9202(5), b = 27.197(1), c = 17.0116(7) ? b = 100.588(1), V = 5875.9(4) 3, Z = 4, C63H57N7O12Cu3, Mr = 1294.78, Dc = 1.464 g/cm3, m = 1.146 mm-1, F(000) = 2668, R = 0.0784 and wR = 0.1546 for 6926 observed reflections with I > 2s(I). The differences of coordinate bond lengths are observed between anhydrous and hydrous units: in the former unit, the average bond lengths are 1.978 ?for CuN (azomethine), 1.883 ?for CuO (phenolic) in Schiff-base moiety, 1.959 ?for CuO (keto), and 1.919 ?for CuO (hydroxy) in hydroxypyridinone moiety; while those in the latter are longer with the following corresponding values: 1.985(5), 1.908(5), 1.993(5) and 1.919(4) ? respectively. The Cu(2)O (water) bond length is 2.375(6) ? 展开更多

The crystal structure N-methyl-9-(4-bromophenyl)-1,8-dioxo-1,2,3,4,5,6,7,8,9,10- decahydroacridine(C20H20BrNO2) was determined by single-crystal X-ray diffraction analysis. It belongs to P21/n space group, with a = 10.7999(18), b = 13.845(3), c = 11.4031(3) ?, β = 99.324(4)°, Dc = 1.525 g/cm3, Z = 4, λ = 0.71070 ?, μ(MoKα) = 2.455 mm-1, Mr = 386.28, V = 1682.5(5) ?3, F(000) = 792, the final R = 0.0463 and wR = 0.1053. In the crystal structure, the pyridine ring adopts a boat conformation, the two six-numbered rings fused with pyridine ring adopt twisting boat con- formation. 展开更多
