H.-M. Hu, D.-L. Long, H.-Y. Zeng, W.-D. Cheng and J.-S. Huang

Synopsis: The crystal structure of the title compound has been redetermined. It crystallizes in space group P1, which is the main difference from the previous determination [O'Connor, Eduok, Owens & Stevens (1986). Inorg. Chim. Acta, 117, 175-181].

Formula: [Cu(ClO4)2(C6H8N2)2]

5-Ethyl-2-phenyl-1-(2,4,6-trichlorophenyl)-3-trifluoromethyl-1H-1,2,4-triazolium hexachloroantimonate

X.-J. Liu, Y.-B. Fan, Y. Liu and Q.-R. Wang

Synopsis: The title compound has interesting biological activity. The three rings in the molecule are planar, with dihedral angles between their least-squares planes of 74.17, 65.15 and 90.69°. In the triazolium ring, the C-N bond lengths are almost equal, with values ranging between 1.315 and 1.340Å; this is due to [bold pi] interaction.

Formula: (C17H12Cl3F3N3)[SbCl6]

A. Linden and S. Bienz

Synopsis: The title compound, N-4-[(benzenesulfonyl)amino]butylbenzenesulfonamide, is useful in the synthesis of natural or unnatural polyamine derivatives. The molecule is centrosymmetric with a straight-chain alkane core, and N-H...O intermolecular hydrogen bonds link the molecules into an infinite two-dimensional network.

Formula: C16H20N2O4S2

3[beta],4[beta]-Epoxy-7-oxo-7a-oxa-7a-homo-5[beta]-cholan-24-oic acid

A. D. Morales, S. García-Granda, R. P. Gil and F. Coll-Manchado

Synopsis: In the title compound, the epoxy O atom is [beta]-oriented. The presence of the epoxy group disturbs the chair conformation in ring A of the steroidal nucleus. Ring A has a half-chair conformation. The seven-membered B-ring conformation is midway between chair and twist-chair. The A/B junction is cis, and the B/C and C/D junctions are both trans. The molecules are held together by intermolecular O-H...O hydrogen bonding, forming a zigzag chain along the [010] direction.

Formula: C24H36O5

Acta Cryst. (1999). C55, IUC9900042    [ doi:10.1107/S0108270199099436 ]


A. D. Morales, S. García-Granda, M. A. Iglesias-Arteaga and F. Coll-Manchado

Synopsis: In the title compound, the Br atom is [beta]-equatorially oriented. The six-membered rings (A, B, C and F) have the expected chair conformations. The D-ring conformation is midway between a 14[alpha]-envelope and a 13[beta],14[alpha]-half-chair, and the E-ring conformation is midway between an O2[alpha]-envelope and a C21[beta],O2[alpha]-half-chair. The packing of the molecules is assumed to be mainly dictated by van der Waals forces. The closest intermolecular contact between non-H atoms is 3.300(9)Å.

Formula: C27H39BrO4

K. Benakli, M. P. Crozet, P. Vanelle and M. Giorgi

Synopsis: In the crystal structure of the title compound, the five- and six-membered rings, together with the nitro substituent, are almost in the same plane. The torsion angle around the bond linking the aromatic ring and the Cl atom is 128.1(3)°.

Formula: C13H12ClN3O2

M. Umehara, H. Hosomi and S. Ohba

Synopsis: The title compound was obtained as a by-product in the chlorination of a C5-C8 fused-ring compound. The formation of a cyclopropane ring, expected from 1H NMR spectroscopic analysis, was confirmed. The junction at the C-C bond between the seven- and three-membered rings is cis.

Formula: C13H18O2
