The synthesis of the calix[4]arene derivative containing 1,3-diketo moieties via direct Claisen condensation without protection of the unsubstituted phenolic OH groups is reported. Single crystal X-ray diffraction analysis reveals that the calix unit to be in a cone conformation incorporating two 1,3-diketo subunits disposed in alternate position at the lower rim. And the crystal packing reveals that the overall packing of the complex is staggered anti-parallelly.

The compound 3,3′-bi(1,1′-dinaphthyl-camphopyrazole) 1, C42H42O4, was obtained in good yield and structurally characterized by 1H and 13C NMR spectroscopy, elemental analysis, and X-ray diffraction. It consists of a 3,3′-bipyrazole group with each pyrazole ring containing a fused camphor group and a naphthalene ring bonded to the adjacent nitrogen atom in the ring. Both of the trimethyl, 5-membered rings of the fused camphor group form an envelope with the apex carbon atom as the flap in each case. In the crystal, weak π–π stacking interactions are observed between nearby 6-carbon rings of the two naphthalene rings linking the molecules into extended chains. Weak π–ring intermolecular interactions are also observed between naphthalene atoms and pyrazole rings from each of the groups helping to stabilize the crystal packing. No classical hydrogen interactions are formed.

(PPh4)2[Sb2Br8] can be prepared from SbBr3 and PPh4Br in CH2Br2 or from Sb2S3, PPh4Br and HBr in 1,2-dichloroethane. Its crystal structure was de­termined with X-ray diffraction data (2764 observed reflexions, R = 0.039). Crystal data: triclinic, space group P1̄, a = 1024.9. b = 1127.1, c = 1282.4 pm, α = 111.80, β = 94.52, γ = 106.92°, Z = 1. The centrosymmetric [Sb2Br8]2- ions consist of two square pyramids sharing a basal edge. The cations are grouped to (PPh4+)2 pairs similarly as in (PPh4)2[As2Cl8]; although the latter compound has a comparable general crystal packing, it is not isotopic. IR and Raman spectral data are reported.

A gold(III) salt of composition [AuCl2(C12H8N2)]PF6was prepared and characterized by elemental and mass spectrometric analysis (ESI(+)–QTOF–MS),1H nuclear magnetic resonance measurements and by single-crystal X-ray diffraction. The square-planar coordination sphere of AuIIIcomprises the bidentate 1,10-phenanthroline ligand and two chloride ions, with the AuIIIion only slightly shifted from the least-squares plane of the ligating atoms (r.m.s. = 0.018 Å). In contrast to two other previously reported AuIII-phenantroline structures that are stabilized by interactions involving the chlorido ligands, the packing of the title compound does not present these features. Instead, the hexafluoridophosphate counter-ion gives rise to anion...π interactions that are a crucial factor for the crystal packing.

AbstractThe mixed cation triel borate Ga4In4B15O33(OH)3 was synthesized in a Walker-type multianvil apparatus at high-pressure/high-temperature conditions of 12.5 GPa and 1300°C. Although the product could not be reproduced in further experiments, its crystal structure could be reliably determined via single-crystal X-ray diffraction data. Ga4In4B15O33(OH)3 crystallizes in the tetragonal space group I41/a (origin choice 2) with the lattice parameters a = 11.382(2), c = 15.244(2) Å, and V = 1974.9(4) Å3. The structure of the quaternary triel borate consists of a complex network of BO4 tetrahedra, edge-sharing InO6 octahedra in dinuclear units, and very dense edge-sharing GaO6 octahedra in tetranuclear units.

A novel metalorganic coordination polymer, namely [Co3(bpd)5.5(NCS)6(NH3)]n2H2O (1) (bpd=1,4-bis (4-pyridyl)-2,3-diaza-1,3-butadiene), has been synthesized and characterized by elemental analyses, infrared spectroscopy, and single-crystal X-ray diffraction. Compound 1 presents 2D[3,4,-connected 3-nodal net with the point symbol (4268210)(4462)(8210). In addition, four identical 2D single nets is interlocked with each other in parallel, thus directly leading to the formation of a polycatenated layer (2D2D).
