When hexymethylbenzene-cyclopentadienyl-iron reacts with ozone in dichloromethane, the title compound is one of the products. Its crystal structure was determined by X-ray diffraction (R = 0.145 for 1412 unique reflexions). Crystal data: a = 1815.1(8), b = 1314.8(5), c = 1823.0(8) pm, space group Pbca, Z = 8. The sandwich-like [η6-C6Me6Fe-η5-C5H5]+ ions exhibit large thermal motions, and the CH2C12 molecules are disordered in two orientations. The novel [Fe2Cl6]2- ion has the structure of two tetrahedra sharing an edge. Its IR spectrum is reported.

The crystal structure of the title compound, obtained as a coating from a lime kiln, has been shown to be isostructural with that of the mineral silicocarnotite and refined by full-matrix least-squares methods (570 independent diffractometer reflections). The lattice parameters of the latter compound were used to initiate the procedure, the final residual being 0.042. The correspondence in detail between the two structures is close. Crystal data: orthorhombic, Pcmn, a = 10.182(1), b = l5.398(2), c = 6.8500(9) �, Z = 4.

The X-ray powder diffraction data of polycrystalline fibrillar zinc trimolybdates ZnMo3O10·3.75H2O, ZnMo3O10·5H2O, and ZnMo3O10·10H2O, are reported. An uncommon diffraction pattern was recorded in the case of the “wet fibers” of ZnMo3O10·10H2O, which could be indexed assuming a model of parallel fibers with translation disorder along the fiber axis. The powder diffraction patterns, lattice parameters, space groups, and other data describing these compounds are presented in this paper.© 1999 International Centre for Diffraction Data.

The crystal structure of the title compound, [Cu(C12H8N2)2I]I,S8, has been determined by X-ray diffraction at 295(1) K and refined by least squares to R 0.066 (2031 ?observed? reflections). ��� Crystal data: orthorhombic, Pbcb, a 7.984(5), b 16.690(4), c 22.986(12) Ǻ, Z 4. ��� The structure comprises five-coordinate trigonal bipyramidal [Cu(phen)2I]+ cations (I equatorial) lying on the 2 axes parallel to a which pass through the Cu-I bonds, together with iodide anions, and lattice S8 molecules, also lying on 2 axes but parallel to b. In the cation, Cu-I is 2.672(3), Cu-N (equatorial) 2.10(1) and Cu-N (axial) 2.00(1) Ǻ. S-S ranges from 2.004(7) to 2.059(7). There appears to be no significant interaction between the octasulphur molecules and any other species.

Compound C

The crystal structure of the title compound, C11H10N4, comprises molecules in a trans conformation for which all the atoms are located in general positions. The six-membered rings are coplanar and this arrangement might be stabilized by intramolecular N—H...N hydrogen bonding. In the crystal, the molecules are linked into helical chains parallel to the b axis via N—H...N hydrogen bonding. The molecular packing shows a herringbone-like pattern along the a axis. Comparison of the X-ray powder diffraction with that calculated from single crystal data proves that a pure crystalline phase was obtained and UV–Vis measurements reveal that only the trans isomer is present.
