CsPd2Cl5 − A New Structural Type Containing∞1[(PdCl3/2Cl)2−] Chains

Abstract

CsPd2Cl5 has been obtained by hydrothermal reaction of cesium chloride and palladium chloride in a 1:2 ratio in quartz glass ampoules at 150 °C. Its crystal structure has been determined by single‐crystal X‐ray diffraction analysis [Pnma, Z = 4, a = 15.725(3) Å, b = 10.526(2) Å, c = 5.275(1) Å]. CsPd2Cl5 represents the first example of a new structural type made up of infinite ∞1[(PdCl3/2Cl)2−] chains, in which PdCl4 units are connected through their edges as well as their vertices.

A new supramolecular semiconductor palladium(ii) complex [(CH3)3N(CH2)3Br]2Pd2Cl6: structural study, optical and electrical properties

“…20,21 Lead-free halogenometallate complexes based on halo-palladate hybrids, with non-toxicity, light-absorbance, and high stability, are good candidates to replace the leadbased perovskites in electrical, semiconducting, and optoelectronic applications. [22][23][24] These hybrid materials have different crystal structures with various possibilities of connections between the adjacent palladium halide octahedra, which can construct either discrete monomeric/dimeric (0D) or extended polymeric chains through corner-, edge-, and/or face-sharing. Several inorganic frameworks can be controlled with numerous organic cations and halides, leading to adjustable physical properties.…”

“…Pd-based hybrid compounds with formula A 2 PdX 4 , with A as the organic cation and X as the halogen, have been applied as light absorbers in solar energy, medical, catalytic, electronic, and energy-saving applications, which can replace lead-based materials. [24][25][26] Recently, new materials based on palladium have been actively investigated to understand the relationship between the structure and the physical properties. 27,28 As a part of this research on the design and synthesis of new palladium complexes with the 3-bromopropyltrimethylammonium cation, the halogen (Br) allows to create new halogen-halogen bonds between the two organic and metallic entities and makes it possible to improve the conductivity of the material.…”

Band-Gap Tuning of Organic–Inorganic Hybrid Palladium Perovskite Materials for a Near-Infrared Optoelectronics Response

“…Multiabsorption was observed in the composite film because of the band gap difference between BiI 3 and (CH 3 NH 3 ) 3 Bi 2 I 9 perovskite. The crystal structures of CsPdCl 3 17 and CsPd 2 Cl 5 18 have been investigated by X-ray diffraction (XRD) methods. However, photoelectric response of the palladium perovskite materials has not been reported.…”
