Stoichiometry mechanosynthesis and interconversion of metal salts containing [CuCl₃(H₂O)]⁻ and [Cu₂Cl₈]⁴⁻

Abstract

The mechanochemical interconversion of two salts was achieved by the addition of an appropriate amount of one of the corresponding components (HL or CuCl2·2H2O), and the progress of dynamic interconversion was revealed by PXRD, fluorescence and Raman spectroscopy.

Solid-state reaction among [CoCl4]2−, [CuCl4]2− and [CuCl4(H2O)]2− ions through transmetalation and liquid-assisted grinding

“…The solid-state reaction took place after severe changes in the coordination environment and geometry of the [CuCl 4 ] 2− dianion which changes into a triangular bipyramid [CuCl 4 (H 2 O)] 2− dianion. In this work, we have demonstrated another good example of excellent control of the synthesis of stoichiometric MOSs, 37,38 especially the transformation of the three anions [CoCl 4 ] 2− , [CuCl 4 ] 2− and [CuCl 4 (H 2 O)] 2− in the solid-state. It is worth mentioning that it has provided a new synthesis method for MOSs in the solid state, which could not be prepared by solution-based methods.…”

“…As we all know, mechanochemistry is a good way to control the solid-state synthesis of metal organic salts with stoichiometric variations. 37 So, we manually ground together salt 3 and CuCl 2 ·2H 2 O in a molar ratio of 1 : 1 in an agate mortar with a drop of MeOH and concentrated HCl. PXRD showed that a new phase has been obtained different from salt 3 (Fig.…”

Metalo-Hydrogen-Bonded Organic Frameworks (MHOFs) Self-Assembled by Second-Sphere Coordination for Guest Exchange

“…Occasionally, isostructural structures are obtained with similar molecular arrangements, space groups, unit cells, and crystal habits, despite slight differences in the components. 36,37 Building on our previous research, 33,34 in this study, we aim to synthesize materials featuring 1D channels by selfassembling the V-shaped diamine ligand L (4,4′-methylenedianiline) with various metal anions, specifically [CdCl 6 ] 4− , [PdCl 4 ] 2− , [PdBr 4 ] 2− , and [SnCl 6 ] 2− using SSC techniques (Scheme 1). Our objectives are to elucidate the role of hydrogen bonding in the formation of these 1D channels, to assess the impact of the anions on the construction of metalohydrogen-bonded organic frameworks (MHOFs), and to analyze the behavior of guest exchange within these frameworks.…”

A mixed-valence copper chloride coordination polymer composed of one-dimensional cationic and anionic substructures

“…The structure differs from typical coordination polymers based on chlorides in a remarkable way. [14][15][16][17][18][19][20][21] The coordination geometry of the Cu II site in the cationic [Cu II Cl 2 (Hdatrz) 2 ] 2+ substructure adopts a "Jahn-Teller" type elongated octahedron. In the cationic structure, two Cl ligands and two N donors from the two Hdatrz ligands are placed on the equatorial plane, while two Cl ligands occupy the axial positions.…”
