Three compounds,[(C2H5) 4N] 2 [HgCl4],[(C2H5) 4N] 2 [CdCl4] and [(C2H5) 4N] 2 [ZnCl4],
have been investigated by means of single-crystal X-ray diffraction. They are isomorphous at …

By means of differential scanning calorimetry, we analyze the sequence of structural phase
transitions and changes which occur in the compounds with M= Cu. Zn, Ni, Co, Cd, Hg. In …

The dielectric constant ϵ and the dielectric loss tan δ of (p‐Cl‐anilinium) 2MnCl4 as function
of temperatures (280 to 370 K) and frequencies (10 Hz to 10 kHz) are investigated. The …

The X-ray powder diffraction pattern indicates that at room temperature,[N (C2H5) 4] 2CoCl4
crystallized in the tetragonal system with the space group P 4/mmm (D 4 h). The chemical …

Abstract Bis (para-toluidinium) 2 tetrachlorocuprate and bis (para-chloroanilinium) 2
tetrachlorocuprate crystallize in a perovskite-related layer structure. The former crystallizes …

The crystal structure [(C 2 H 5) 4 N] 2 CuCl 4 has been determined by X-ray diffraction at
243K. The room temperature phase (phase I) belongs to the space group P4 2/nm [1] …

The crystal [N (C2H5) 4] 2CuCl4 was grown from methanol solution and revealed phase
transitions already on the first cooling. DTA measurements provided the evidence for the …

Room‐temperature polarized Raman spectra of a single crystal and IR spectra of a
polycrystalline sample were measured for [N (C2H5) 4] 2MnCl4 and the assignment of the …

The discontinuous order-disorder structural instabilities occurring in TEA2BCl4 with B= Zn,
Cu, Hg are studied by means of X-ray diffraction, polarized light microscopy, and from the …

The title compound contains four isolated and discrete moieties: ie two independent [(CH3)
4N]+ cations, with one ordered on a\overline {4} axis and the other disordered with the …
