Synthesis and structural properties of a 2D Zn(ii) dodecahydroxy-closo-dodecaborate coordination polymer

Abstract

In this work, we discuss the synthesis and characterization of a 2D coordination polymer composed of a dianionic perhydroxylated boron cluster, [B12(OH)12]2-, coordinated to Zn(II)—the first example of a transition...

Expanding Linker Dimensionality in Metal‐organic Frameworks for sub‐Ångstrom Pore Control for Separation Applications

“…[27,28] Popular carborane 3D-linkers include variations from either the m-or p-carborane core, varied in either their length, [29,30] geometry, [31][32][33] topacities [34] or coinciding functionalities. [35][36][37]…”

“…Proving to be a similar, versatile building block is the carborane molecule, comprising a carbon‐boron icosahedral cluster and occupying the same volume as a rotated phenyl ring [27, 28] . Popular carborane 3D‐linkers include variations from either the m ‐ or p ‐carborane core, varied in either their length, [29, 30] geometry, [31–33] topacities [34] or coinciding functionalities [35–37] …”

Electrochemical Cycling of Redox-Active Boron Cluster-Based Materials in the Solid State

“…Despite these advances, the incorporation of other well-defined covalent-based systems into electrochemically active materials in the solid state has been fundamentally underexplored. For example, polyhedral boron clusters, which are often described as three-dimensional aromatic analogues of benzene, can exhibit well-defined redox properties in solution, as seen for boranes ([B n H n ] 2– ; n ≤ 12), carboranes, and their numerous functionalized derivatives. − Historically, a number of boron-based clusters have been deemed redox-inert species with wide electrochemical stability windows, prompting early studies of Li 2 B 12 Cl 12 and Li 2 B 10 Cl 10 as novel electrolytes, first in SOCl 2 , and later in ethereal solvents. − More recently, there have been extensive efforts in developing some of these clusters for solid-state electrolyte applications. − …”

Locking water molecules via ternary O–H⋯O intramolecular hydrogen bonds in perhydroxylated closo-dodecaborate

“…42–44 The per-hydroxylated closo -dodecaborate B 12 (OH) 12 2− bearing twelve organic linkers has intriguing properties that find applications in various fields, e.g. , molecular cross-linking skeletons, 45 electrolyte materials, 46 coordination polymers, 47 and magnetic resonance imaging (MRI) contrast agents. 48 Despite its fundamental role in multitudinous research areas, the intrinsic electronic structure and related anionic HB in micro-solvation still need to be investigated.…”
