Synthesis, crystal structure, thermal and dielectric properties of bis(p-phenylenediammonium) chloride hexachlorobismuthate(III) monohydrate [C6H4(NH3)2]2ClBiCl6.H2O

Abstract

Synthesis, crystal structure, and dielectric properties of [C 6 H 4 (NH 3 ) 2 ] 2 ClBiCl 6 .H 2 O are reported. The compound crystallizes in the monoclinic system with space group P2 1 /n. The unit cell dimensions are a=9.836(5), b=19.582(5), c=13.082(5) Å, β=104.731(5)°with Z=4. The atomic arrangement can be described by an alternation of organic and inorganic layers. The anionic layer is built up of octahedral of [BiCl 6 ] 3-arranged in sandwich between the organic layers. The crystal packing is governed by means of the ionic N-H···Cl hydrogen bonds, forming a threedimensional network. The dielectric properties have been investigated at temperature range from 297 to 410 K at various frequencies (10 Hz-100 kHz). Dielectric studies were performed to confirm results obtained with thermal analysis. The evolution of dielectric constant as a function of temperature and frequency of single crystal has been investigated in order to determine some related parameters.

“…Furthermore, the distance between two aromatic nucleus was 6.617 Å > 3.8 Å (Fig. 6), which confirms that the π-π interaction are absent in this compound [26].…”

Color Change Effect in an Organic–Inorganic Hybrid Material Based on a Porphyrin Diacid

“…Bi-Cl distances found in 1 range from 2.514 to 3.152 Å. This is a more extreme range than typically observed in isolated [BiCl6] 3-anions, for example in [C6H4(NH3)2]2ClBiCl6•H2O 74 (Bi-Cl distances from 2.551 to 2.930 Å) but well within the range of bond lengths found in compounds containing multinuclear chloridobismuthate anions such as (BzV)5[Bi3Cl14]2 (BzV 2+ = N,N′-dibenzyl-4,4′-bipyridinium) 78 where Bi-Cl distances range from 2.544 to 3.176 Å. As found in many halogenidometalate compounds, the shortest and longest bonds are trans to each other in the [BiCl6] 3-anions in compound 1.…”

“…Bi-Cl bond length and Cl-Bi-Cl angles in the respective crystal structures often show a tendency towards distortion when participating in hydrogen bonding interactions. [71][72][73][74][75][76][77] As shown in Figure 1 This range corresponds to decay times which can be reliably asserted by our measurement, while no access is given to decay components with time constants shorter than our temporal resolution.…”

“…Bi-Cl bond length and Cl-Bi-Cl angles in the respective crystal structures often show a tendency towards distortion when participating in hydrogen bonding interactions. [71][72][73][74][75][76][77] As shown in Figure 1 (a), the [H6TPyP] 6+ cations form stacks along the b axis. Sandwiched in between the cations are highly distorted [BiCl6] 3-anions.…”

Growth, crystal structure, Hirshfeld surface and vibrational properties of a new supramolecular hybrid material: (C4H7N2)2TeBr6

“…They are characterized by a large variety of structures framework dimensionality build from chains, layers, or three-dimensional connections [5,6] as well as a correlation between the structural features and a vast diversity of physical properties from their potential applications such as magnetic, optical, luminescence and electric [7][8][9][10][11]. Hybrid halogen-based materials have demonstrated exciting properties from the renewal of zero-dimensional structures belonging to alums and Tutton's salts [12][13][14][15]. In addition, Tellurium metalloid, as a strong Lewis acid, has an extensive coordination chemistry [16][17][18].…”
