TL;DR: In this article, three bismuth(III) thiolate complexes of 2-mercaptoethanol (H2meret) were synthesized and X-ray structure determination of 1 and 2 showed that both complexes have one-dimensional polymeric structures where thiolato-S atoms bridge Bi atoms in 1 and alkoxo-O atoms bridge them in 2.
Journal ArticleDOI
Refinement of the Crystal Structure of NH4H2PO4 above and below Antiferroelectric Phase Transition Temperature
TL;DR: Au-dessus de la temperature de transformation de phase antiferro-electrique (Tc=148 K), NH 4 H 2 PO 3 cristallise avec le groupe d'espace I42d (R=1,7%).
Journal ArticleDOI
Structural phase transition, ionic conductivity, and dielectric investigations in K3H(SO4)2 single crystals
TL;DR: In this paper, the authors investigated the dielectric properties of K 3 H(SO 4 ) 2 crystal in the temperature range between 25 and 300°C and found that the electrical conductivity increases with increasing temperature and the sample crystal becomes a fast ionic conductor at the temperatures above 206°C.
Journal ArticleDOI
Frequency dependence of ionic conductivity and dielectric relaxation studies in Na3H(SO4)2 single crystal
TL;DR: In this article, electrical impedance measurements of Na 3 H(SO 4 ) 2 were performed as a function of both temperature and frequency and the electrical conductivity and dielectric relaxation were evaluated.
