Perplexing Coordination Behaviour of Potentially Bridging Bipyridyl-Type Ligands in the Coordination Chemistry of Zinc and Cadmium 1,1-Dithiolate Compounds

“…O(hydroxyl) hydrogen bonding, involved all hydroxyl groups as acceptors and donors, leading to a three-dimensional architecture, Figure 9. As discussed in the original publication, there are no solvent accessible voids in 45 and the key crystal indicators, that is density (1.709 compared with 1.570 g/cm 3 ) and packing efficiency (74.9 compared with 71.6%), suggest that 46 represents a less efficient packing arrangement, owing to the presence of dioxane molecules. Consistent with this is the lack of strong intermolecular interactions between the host lattice and the dioxane molecules resident in the channels.…”

“…The rationale for the formation of 46 rests with the observation that owing to the high boiling point of dioxane, the dioxane molecules were trapped in the crystal under the conditions of specific crystallisation experiment [60]. 3 ) and packing efficiency (74.9 compared with 71.6%), suggest that 46 represents a less efficient packing arrangement, owing to the presence of dioxane molecules. Consistent with this is the lack of strong intermolecular interactions between the host lattice and the dioxane molecules resident in the channels.…”

“…While these were initially in the realm of materials science with applications relating to energy and gas storage, photo-responsive materials, catalysis, etc. [3][4][5][6][7], there are increasing applications of coordination polymers relevant to bioinorganic chemists. Examples include coordination polymers functioning as carriers for drug In this bibliographic review, the structural chemistry of zinc and cadmium 1,1-dithiolates and bipyridyl-type ligands is surveyed.…”

Design Strategies toward Advanced MOF‐Derived Electrocatalysts for Energy‐Conversion Reactions

“…These are: 1) the carbon matrix obtained from the organic framework is able to act as a highly conductive network, promoting fast electron transfer; [31][32][33][34][35][36] 2) various heteroatoms (e.g., N, O, S, and P) contained in the organic ligands can be directly doped into the carbon framework, which can not only provide more active sites, but also create a favourable microenvironment for the growth of functional nanoparticles (NPs, e.g., transition metal carbides, nitrides, and oxides); [24,[36][37][38][39][40][41] 3) the metal atoms in MOFs can form corresponding metals and/or compounds and homogeneously distribute in the carbon network, leading to the in situ synthesis of a carbon framework decorated with transition metals and/or transition metal compounds; [24,[41][42][43] 4) a well-defined morphology, size, and structure can be obtained by adjusting synthesis parameters; [42][43][44][45] 5) many of the features (e.g., large surface area and high porosity) inherited from the MOF precursors can be preserved in the resultant materials after post-treatments. [46][47][48] Unsurprisingly, owing to the advantages discussed above, these MOF-derived materials have stimulated much interest in energy fields, [49][50][51] and have been studied as electrode materials in batteries and supercapacitors. [49,50] Recent progress in these two attractive technologies has been comprehensively reviewed by Lu et al [50] Another very important application is electrocatalysis.…”

[49,50] Recent progress in these two attractive technologies has been comprehensively reviewed by Lu et al [50] Another very important application is electrocatalysis. [51] In particular, as promising substitutes for noble-metal-based electrocatalysts, MOF-derived materials have been extensively investigated as alternative electrocatalysts for the ORR, OER, and HER, and have made many great achievements during the past decade.…”
