3-Acetyl-5-hy-droxy-2-methyl-anthra[1,2-b]furan-6,11-dione.

ABSTRACT: The asymmetric unit of the title compound, C(19)H(12)O(5), contains two independent mol-ecules, both slightly buckled along an axis passing through the C=O bonds of the anthraquinone ring system (r.m.s. deviation of non-H atoms = 0.082 and 0.148?Å): the benzene rings are twisted to each other by 4.3?(3)°in one mol-ecule and 10.6(3)° in the other. In both mol-ecules, the hy-droxy group forms an intra-molecular O-H?O hydrogen bond. The two independent mol-ecules inter-act by ?-? stacking with a centroid-centroid distance of 3.539?(2)?Å between hy-droxy-benzene rings of adjacent mol-ecules.

Crystal structure of bis-{?-4-methyl-N'-[3-(oxido-imino)-butan-2-yl-idene]benzene-sulfono-hydrazidato}bis-[(dimethyl sulfoxide-?O)copper(II)].

Project description:In the title compound, [Cu2(C11H13N3O3S)2(C2H6OS)2], the Cu(II) cation is N,N',O-chelated by a deprotonated hy-droxy-imino-tosyl-hydrazone ligand and coordinated by a dimethyl sulfoxide mol-ecule. One O atom from the adjacent hy-droxy-imino-tosyl-hydrazone ligand bridges the Cu(II) cation, forming the centrosymmetric dimeric complex. The cation is in an overall distorted N2O3 square-pyramidal coordination environment. The methyl-benzene ring is twisted with respect to the hydrazine fragment, with a dihedral angle of 89.54?(9)° between the planes. An intra-molecular C-H?O hydrogen bond occurs. In the crystal, mol-ecules are linked by weak C-H?O and C-H?S inter-actions. Weak ?-? stacking is also observed between parallel benzene rings of adjacent mol-ecules, the centroid-centroid distance being 3.9592?(17)?Å.

Project description:In the title compound, [Fe(C44H24Cl4N4)(H2O)2](SO3CF3)·C8H8O3·2H2O, the Fe(III) cation is chelated by the four N atoms of the deprotonated tetra-kis-(4-chloro-tetra-phen-yl)porphyrin (TClPP) and further coordinated by two water mol-ecules in a distorted octa-hedral geometry. In the crystal, the cations, anions, 4-hy-droxy-3-meth-oxy-benzaldehyde and water mol-ecules of crystallization are linked by classical O-H?O hydrogen bonds and weak C-H?O and C-H?Cl hydrogen bonds into a three-dimensional supra-molecular architecture. The crystal packing is further stabilized by weak C-H?? inter-actions involving pyrrole and benzene rings. ?-? stacking between parallel benzene rings of adjacent 4-hy-droxy-3-meth-oxy-benzaldehyde mol-ecules is also observed, the centroid-centroid distance being 3.8003?(13)?Å. The three F atoms of the anion are disordered over two sets of sites, with a refined occupancy ratio 0.527?(12):0.473?(12). The O atom of one water mol-ecule of crystallization is also disordered over two positions in an occupancy ratio of 0.68?(5):0.32?(5).

(2-Hy-droxy-acetato-?O)bis-(1,10-phenan-throline-?N,N')copper(II) nitrate.

Project description:In the title compound, [Cu(C(2)H(3)O(3))(C(12)H(8)N(2))(2)]NO(3), the Cu(II) atom is coordinated by two phenanthroline (phen) ligands and one carboxyl-O atom of a hy-droxy-acetate anion in a distorted square-pyramidal geometry. The hy-droxy group of the hy-droxy-acetate ligand links with the counter NO(3) (-) anion via a pair of bifurcated O-H?O hydrogen bonds. The centroid-centroid distance of 3.5676?(14)?Å between benzene rings of parallel phen ligands of adjacent mol-ecules suggests the existence of ?-? stacking. Weak inter-molecular C-H?O hydrogen bonding is also present in the crystal structure.

Crystal structure of 4-({5-[(E)-(3,5-di-fluoro-phen-yl)diazen-yl]-2-hy-droxy-benzyl-idene}amino)-2,2,6,6-tetra-methyl-piperidin-1-ox-yl.

Project description:The asymmetric unit of the title compound, C22H25F2N4O2, contains two crystallographically independent mol-ecules. In one mol-ecule, the two benzene rings are oriented at a dihedral angle of 1.93?(10)° and in the other mol-ecule the corresponding dihedral angle is 7.19?(9)°. The piperidine rings in the two mol-ecules adopt a similar distorted chair conformation, and both have pseudo-mirror planes passing through the N-O bonds. An intra-molecular O-H?N hydrogen bond between the hy-droxy group and the imine N atom is observed in both mol-ecules. In the crystal, weak C-H?O and C-H?F hydrogen bonds, enclosing R 2 (2)(6) ring motifs, and weak ?-? stacking inter-actions link the mol-ecules into a three-dimensional supra-molecular network, with centroid-to-centroid distances between the nearly parallel phenyl and benzene rings of adjacent mol-ecules of 3.975?(2) and 3.782?(2)?Å.

Methyl 5,7-dihydr-oxy-2,2,9-trimethyl-6,11-dioxo-6,11-dihydro-2H-anthra[2,3-b]pyran-8-carboxyl-ate.

Project description:The title compound, C(22)H(18)O(7), also known as laurentiquinone B, is a new anthraquinone which was isolated from Vismia laurentii, a Cameroonian medicinal plant. The asymmetric unit contains two independent mol-ecules. Each of them contains four fused rings, three of which are coplanar and typical of anthracene, while the heterocyclic rings adopt envelope conformations. Intra-molecular O-H?O hydrogen bonds result in the formation of two planar rings, which are also almost coplanar with the adjacent rings. In the crystal structure, inter-molecular O-H?O and C-H?O hydrogen bonds link the mol-ecules and a ?-? contact is also present [centroid-centroid distance = 3.967?(3)?Å].

(Z)-1-[(2E)-3,4-Diphenyl-2,3-di-hydro-1,3-thia-zol-2-yl-idene]-2-[1-(4-hy-droxy-phen-yl)ethyl-idene]hydrazinium bromide including an unknown solvate.

Project description:In the title compound, C23H20N3OS(+)·Br(-), the di-hydro-thia-zole ring (r.m.s. deviation = 0.015?Å) is twisted with respect to each of the C- and N-bound phenyl rings and the hy-droxy-benzene ring, making dihedral angles of 76.0?(2), 71.2?(2) and 9.8?(2)°, respectively. In the crystal, inversion-related mol-ecules are linked by association of the bromide ions with the cations via N-H?Br and O-H?Br hydrogen-bonding inter-actions. These mol-ecules run in channels parallel to the a axis through face-to-face ?-? stacking inter-actions between the hy-droxy-benzene rings [centroid-centroid distances = 3.785?(3)?Å] which, in turn, are connected into layers parallel to (110) by weak C-H?? inter-actions. A small region of electron density well removed from the main mol-ecule and appearing disordered over a center of symmetry was removed with PLATON SQUEEZE [Spek (2009 ?). Acta Cryst. D65, 148-15] following unsuccessful attempts to model it as plausible solvent molecule. The nature of the solvent was not known and hence, this is not taken into account when calculating M r and related data.

In the crystal, weak C-H?O and C-H?Cl inter-actions are observed.
