Intercalation of Organic Molecules into Vanadium(IV) Benzenedicarboxylate: Adsorbate Structure and Selective Absorption of Organosulfur Compounds

Abstract

A very good host: The guest acid molecules of hydrothermally synthesized [V(O)(bdc)](H2bdc)0.71 (bdc=benzenedicarboxylate) are removed to give high‐quality single crystals of [V(O)(bdc)] (1). On absorption of guest molecules from the liquid phase, 1 undergoes crystal‐to‐crystal transformations (aniline: 2; thiophene: 3; acetone: 4). Furthermore, complex 1 also selectively absorbs thiophene and dimethyl sulfide from methane.

Diversity of coordination modes in the polymers based on 3,3′,4,4′-biphenylcarboxylate ligand

“…Among them, polycarboxylates have caught the long lasting research attention, due to their variety coordination modes and structural features, such as 1,2-benzenedicarboxylate, 1,4-benzenedicarboxylate, 1,3,5-benzenetricarboxylate, and 1,2, 4,5-benzenetetracarboxylate, which all have been extensively employed in the construction of metal-organic polymers displaying variety structures and interesting properties [13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29]. So far, many efforts have been focused on the employment of flexible or the V-shaped multidentate organic bridging ligands [30][31][32][33][34][35][36][37][38][39][40], while the influence of the size of the rigid aromatic multidentate ligands on the formation of the ultimate framework have rarely been studied [41][42][43][44][45][46][47][48][49][50][51][52][53][54][55][56][57]…”

Syntheses, structures, and magnetism of two coordination compounds with 3,3′,4,4′-biphenyltetracarboxylic acid and 1,10-phenanthroline

“…Interest is justified for intriguing topologies, structural diversity, such as helixes and diamondoid nets, and potential applications as functional materials, such as heterogeneous catalysis, molecular recognition, magnetism, gas storage, ion exchange, nonlinear optics, and electrical conductivity [1][2][3][4][5][6][7][8][9][10][11][12]. Polycarboxylates are often good candidates as bridging ligands to construct coordination polymers owing to their versatile coordination modes and high structural stability; 1,2-benzenedicarboxylate, 1,4-benzenedicarboxylate, 1,3,5-benzenetricarboxylate, and 1,2,4,5-benzenetetracarboxylate have been widely used to form metal-organic polymers with various structures and properties [13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29]. Considerable efforts have been devoted to developing flexible or V-shaped multidentate bridging ligands [30][31][32][33][34][35][36][37][38][39][40].…”

XPS Study of Sol-Gel Synthesized Vanadium-Titanium-Hydroquinone Oxide Bronze Films

“…The sol-gel process for the production of vanadium oxide bronzes can be described as follows: V 2 O 5 gel is produced, the required element is intercalated to the structure of the gel, and the resulting hydrate is heated up to a temperature that ensures the removal of all water (absorbed, zeolyte type and chemically bonded) from the compound. Layered nanocomposites with conductive polymerized layers were prepared as a result of the intercalation of various molecular compounds into interlayer spaces of vanadium pentoxide gels [16][17][18][19]. In those compounds, the conductive layers were separated by water molecules.…”
