Single crystal structure studies at room temperature have been made for the first stage Mn Cl2 intercalated graphite. The nominal composition was C5·6 Mn Cl2·4, as deduced from chemical analyses and X-ray diffraction intensities. The data are in agreement with the island model, already proposed for Ni Cl2 intercalation. From the decrease in C-C bond length and comparison with As F5 compound, it is shown that the charge transfer is determined by chlorine in excess with respect to free metal halide. 相似文献

Two conducting polyiodide salts have been obtained by direct oxidation of the donor DIPSØ4 by iodine. These salts are characterized by X-ray diffraction, Raman and optical spectroscopy. The nature of iodine species is determined and the degree of charge transfer is evaluated. 相似文献

The physical properties of paramagnetic Mo(V) organometallic radical cation salts, , are investigated through the study of two series of solid solutions incorporating two kinds of anions ( or ). The combination of EPR and X-ray diffraction is used to specify the nature of the structural phase transitions which occur
in the paramagnetic phase and to determine the corresponding (

) phase diagrams. Finally, antiferromagnetic resonance is studied to probe the low temperature antiferromagnetic ground state.
In the last part of the paper, the observed complex phase diagram is analyzed by considering a compressible model with at
least two independent modes of compression. We conclude that the larger compressibilities are associated with the smaller
anions.

Isocyanides react readily with trichloroacetic acid anhydride forming stable hydrates of trichloropyruvamides. These compounds are valuable intermediates for obtaining oxamides by reaction with TMSCl/NEt3 followed by addition of an amine. 相似文献
