摘要:
AbstractThe thermal behaviour of the phases Cu3‐xTe2and CuTe has been investigated by X‐ray diffraction at continuously varying temperature and by differential thermal analysis. Cu3‐xTe2has an orthorhombic structure at room temperature which is closely related to the tetragonal structure of defective Cu2Sb type stable above 140°. Above 360° a face‐centred cubic form was found; the transition tetragonal ⇄ f.c.c. takes placeviaanother (rhombohedral?) form. The atomic arrangements in the orthorhombic and f.c.c. forms have been studied. CuTe was found to disproportionate at 340° into Cu3‐xTe2and a tellu

摘要:
AbstractCrystals of the title compound are monoclinic. The space group is P21//n, the lattice constants area= 11.07,b= 11.38,c= 15.61 Å, β = 98.9° and Z = 4.The structure was solved by the conventional heavy‐atom technique based upon photographic X‐ray data. Intramolecular bond distances and valency angles are listed and appear to be quite regular. The dihedral angle between the phenyl and the cyclohexadiene ring amounts to 56°. The latter ring is slightly distorted towards the boat form. Thetert‐butyl groups exhibiting a pronounced thermal libration about their bonds to the cyclohexadiene ring, are not d

摘要:
AbstractThe compound crystallizes in space group P1, witha= 9.96,b= 8.38 andc= 11.77 Å; α = 73.4, β = 81.3 and γ = 83.5°. There are 2 molecules, related by the centre of symmetry, in the unit cell. Single‐crystal diffractometer, heavy‐atom method and least‐squares refinement were employed. Since only badly shaped crystals could be obtained, interatomic distances and angles are not very accurate. However, the investigation was intended merely to determine the molecular structure. The final weighted R factor is 9.0%, including 1635 three‐dimensional

摘要:
AbstractA number of solvates having the general formula M(R‐BN)n2+(anion−)2is reported. The cations M are the divalent ions: Mg, Mn, Fe, Co, Ni, Cu, Zn and Cd. The substituted benzonitriles R‐BN are: 4‐Cl‐BN, 3‐Cl‐BN, 2‐Cl‐BN, 4‐CH3O‐BN, 2,6‐diCl‐BN, 3,4‐di(CH3O)‐BN and 2,5‐di(CH3)‐BN;nis usually 6 except for Cu2+wherenis found to be 6,5 or 4. One complex of Zn2+is prepared wherenis 4. The anions used are SbCl6−, FeCl4−and InCl4−.The infrared nitrile absorptions are examined and compared with those of the free nitrile. Metal‐nitrogen vibrations are obtained from far‐infrared spectra. Ligand‐

摘要:
AbstractRaman and infrared spectra of aluminium isopropoxide in some liquid and solid forms occurring at room temperature have been investigated. The depolarization ratio of Raman lines has been measured for the liquid.The vibrational spectra are consistent with the occurrence of two molecular forms. In the freshly heated liquid and in the solid melting at 29.5°, probably a trimer is present. The vibrational spectra of this form and of dimeric Al‐t‐butoxide differ distinctly in the range 0‐750 cm−1. In the aged liquid and in the solids melting at 118° or about 137° a partially six‐coordinated tetramer, as proposed byBradley, is the more probable molec
