The final R = 0.030 and wR = 0.078 for 4070 observed reflections (I > 2s(I)), and R = 0.064 and wR = 0.091 for 5516 independent ones. The crystal consists of tetrahedral Fe(II) complex and hydrogen bonded 4,5-diazafluoren-9-one (dafone). The carbonyl bridge in dafone distorts the bipyridine moiety and results in the longer N…N separation of 3.071(3) and 3.061(3) ? There exists an extensive intermolecular hydrogen bond network in the crystal, and p-p stacking is observed between the neighboring dafone rings.展开更多
The polymorphic isomer [Cu(dafone)2(H2O)2](Hphth)2 1 (dafone = 4,5- diazafluoren-9-one, phth = 1,2-benzenedicarboxyl) has been synthesized and the structure was determined by single-crystal X-ray diffraction.

Crystal data: C38H26CuN4O12, monoclinic, space group P21/a with a = 11.5863(18), b = 25.512(4), c = 11.878(2) ?, β = 111.696(3)o, V = 3262.1(9) ?3, Mr = 794.17, Z = 4, Dc = 1.617 g/cm3, F(000) = 1628, μ = 0.748 mm-1, R = 0.0603 and wR = 0.1132 for 6878 observed reflections with I > 2σ(I). 1 consists of one [Cu(dafone)2(H2O)2]2+ cation and two monoprotonated 1,2-benzenedicarboxyl (Hphth) anions and forms a two-dimensional hydrogen bond network via intermolecular hydrogen bond interactions between the coordinated water molecules and carboxylato-oxygen atoms from monoprotonated benzenedicarboxyl anions.展开更多

Compound 1 was isolated from the sponge Polymastia sobustia and compound 2 was obtained from the soft coral Sinularia inexplicata. Their structures were established as 3 beta-hydroxy-stigmast-5en-7-one and 24-methylene cholestan -3 beta, 6 beta, 9 alpha, 19-tetrol by variety of spectral analysis such as IR, EIMS, 1DNMR, H-1-H-1 COSY, HMQC, HMBC, NOESY.展开更多
