The title azine mol-ecule, C28H24N2O4, lies about a center of inversion. The dihedral angle between the phenyl ring and the hy-droxy-substituted ring is 70.3 (5)°. The phenolic O-H group forms an intra-molecular hydrogen bond to the azine N atom.

In the title mol-ecule, C(6)H(4)N(2)O(7), the two nitro groups are tilted with respect to the aromatic ring by 11.2 (1) and 10.9 (1)°. All three hy-droxy groups are involved in the formation of bifurcated intra- and inter-molecular O-H⋯O hydrogen bonds. The crystal packing exhibits short O⋯O distances of 2.823 (2) Å between two O atoms of the nitro groups.

It would clearly be pointless in this lecture either to attempt to list all the papers that have been published on a vast variety of foodstuffs, nor even selecting only a fcw, to describe in detail to a Budapest audience, the apparatus that is commonly used for testing a few of the principal products that have been intensively studied. Under Professor TELEGDy-Kov~.(Ts, pioneer work has been and...

The title compound, [Cd(C(9)H(7)O(3))(2)(C(10)H(8)N(2))(2)], was synthesized under mild hydro-thermal conditions. The structure of the complex mol-ecule consists of four approximately planar fragments: two 3-(3-hy-droxyphenyl)propenoate residues and two 2,2'-bipyridine ligands [largest deviation from the least-squares planes is 0.240 (1) Å for one of 3-(3-hy-droxy-phenyl)propenoate residues]. T...

In the title compound, C(29)H(40)O(3), the enone moiety adopts an s-cis conformation. The dihedral angle between the benzene rings is 4.33 (5)° The least-squares mean line through the tetra-decyl side chain forms a dihedral angle of 83.99 (7)° with the normal to the attached benzene ring. In the crystal, O-H⋯O and C-H⋯O hydrogen bonds involving the keto and the hy-droxy O atoms form ribbons alo...

The asymmetric unit of the title polymeric complex, [Cd(2)(C(13)H(7)NO(4))(OH)(2)](n), consists of two independent Cd(II) atoms, one 5-(4-carb-oxy-phen-yl)pyridine-2-carboxyl-ate ligand and two hy-droxy groups. One Cd(II) atom is six-coordinated by two O atoms from two ligand mol-ecules and by four μ(3)-OH groups in a distorted trigonal-prismatic geometry. The other is five-coordinated by one N...

The title compound, C(18)H(26)O(7), is an eremophilenolide which has been isolated from the plant Ligularia duciformis for the first time. The present study confirms the atomic connectivity assigned on the basis of (1)H and (13)C NMR spectroscopy. The mol-ecule contains three fused rings, two six-membered rings in chair confomations and a five-membered ring in a flattened envelope conformation....
