Project description:In the title compound, C18H16N4, the dihedral angle between the benzene and phenyl rings is 61.40?(4)°. In the crystal, mol-ecules are linked by N-H?N(nitrile) hydrogen bonds, forming inversion dimers. The dimers are further linked by N-H?N(amine) hydrogen bonds, and both units are arranged almost perpendicular to each other [angle between dimer mean planes = 84.43?(12)°]. This arrangement is extended to form a ladder-like structure parallel to the c axis.

Project description:In the title compound, C(15)H(20)ClNO(3), the seven-membered ring adopts a distorted boat-sofa conformation; the methyl-ene C atoms of this ring are coplanar with the benzene ring. Both meth-oxy groups are almost coplanar with the attached benzene ring [C-C-O-C = 6.5?(2) and -13.5?(3)°]. An intra-molecular C-H?O hydrogen bond is observed in the mol-ecular structure. In the crystal structure, a C-H?? inter-action involving the benzene ring is observed.

Project description:In the title compound, C(20)H(12)N(2)O(2), the phenyl and benzene rings are mutually perpendicular, with the dihedral angle between the phenyl rings being 87.92?(16)° and those formed between the phenyl rings and the benzene rings being 73.68?(15) and 84.65?(15)°. Helical supra-molecular chains along [010], mediated by C-H?N inter-actions, are found in the crystal structure.

Crystal structure of 4'-bromo-2,5-dihy-droxy-2',5'-dimeth-oxy-[1,1'-biphen-yl]-3,4-dicarbo-nitrile.

Project description:In the crystal of the title substituted hemibi-quinone derivative, C16H11BrN2O4 or [BrHBQH2(CN)2], the substituted benzene rings are rotated about the central C-C bond, forming a dihedral angle of 53.59?(7)°. The ring systems inter-act through an intra-molecular O-H?Ometh-oxy hydrogen bond, which induces a geometry quite different from those in previously reported hemibi-quinone structures. In the crystal, the mol-ecules associate through an inter-molecular O-H?Nnitrile hydrogen bond, forming chains which extend along [100] and are inter-linked through very weak C-H?N hydrogen bonds, giving a overall two-dimensional structure lying parallel to (010).

5,8-Dimeth-oxy-3,9-dimethyl-3a,4,9,9a-tetra-hydro-4,9-ep-oxy-naphtho-[2,3-d]isoxazole.

Project description:The title compound, C15H17NO4, is the exo isomer with a syn arrangement of the O atom in the isoxazole ring to the methyl group of the bicyclic alkene. The dihedral angle between the isoxazole ring and the benzene ring is 7.42?(9)°. In the crystal, weak C-H?O hydrogen bonds link mol-ecules, forming a three-dimensional network. The isoxazole O atom is an acceptor for both weak hydrogen bonds.

Penta-fluoro-phenyl (3R,4R,5S)-5-{[(3R,4R,5S)-5-azido-methyl-3,4-dimeth-oxy-2,3,4,5-tetra-hydro-furan-3-carboxamido]-meth-yl}-3,4-dimeth-oxy-2,3,4,5-tetra-hydro-furan-3-carboxyl-ate.

Project description:The title compound, C(22)H(25)F(5)N(4)O(9), is a stable penta-fluoro-phenyl ester inter-mediate in the synthesis of novel homo-oligomeric structures containing branched carbon chains. The structure is epimeric to the previously characterized dimeric penta-fluoro-phenyl ester with stereochemistry (3R,4R,5R), which was synthesized using d-ribose as starting material. The crystal structure of the title mol-ecule removes any ambiguities arising from the relative stereochemistries of the six chiral centres. Two hydrogen bonds, bifurcating from the NH group, stabilize the crystal: one intra-molecular and one inter-molecular, both involving O atoms of the meth-oxy groups. The asymmetric unit contains two independent mol-ecules not related by any pseudo-symmetry operators. The major conformational differences are localized, leading to one mol-ecule being extended compared to the other. The collected crystal was twinned (twin ratio is 0.939:0.061), and the azide group is positionally disordered over two positions in one mol-ecule [occupancy ratio 0.511?(18):0.489?(18)].

This induces a geometry different from that predicted by theory, and is unique among the hemibi-quinones heretofore reported.

9-(3,4-Dimeth-oxy-phen-yl)-3,3,6,6-tetra-methyl-4,5,6,9-tetra-hydro-3H-xanthene-1,8(2H,7H)-dione.

Project description:The asymmetric unit of the title xanthene compound, C(25)H(30)O(5), contains two mol-ecules in which the pyran ring and the dimeth-oxy-phenyl ring are nearly perpendicular to one another [dihedral angles = 86.81?(8) and 84.45?(9)°]. One of the meth-oxy groups in one mol-ecule is twisted away from the phenyl ring [C-O-C-C torsion angle = -103.40?(16)°]. The pyran ring adopts a boat conformation whereas the two fused cyclo-hexane rings adopt envelope conformations in both mol-ecules. In the crystal, mol-ecules are linked into a three-dimensional network by C-H?O hydrogen bonds.

The conformations of the chains and their packing differ markedly in the two polymorphs.
