Discrimination between S²⁻ and SO²⁻ Sites in Mixed Crystal Compounds Containing Co and Co/Mo Clusters by ⁵⁹Co-NMR Spectroscopy, and the Relevance for HDS Catalysis

In aqueous solutions of the mixed crystal compounds with formal composition K8[Co4-xMoxS4-y(SO)y(CN)12·nH2O (x = 0–2; y = 0–2) i) there are distinct CoS, Co(SO), and Co(SO)2 sites and ii) no hetero-metal clusters are present. These results, revealed by 59Co–NMR, could principally not be disclosed by single crystal X-ray structure analysis. The NMR data also suggest a stable dinuclear cobalt-sulphur cluster in solution. The relevance for HDS catalysis is discussed

Coordination chemistry under confined conditions: a simplified illustrative view

Müller A, Bögge H, Henry M. Coordination chemistry under confined conditions: a simplified illustrative view. COMPTES RENDUS CHIMIE. 2005;8(1):47-56.Spherical-shaped polyoxomolybdate structures can be synthesized/designed so that they behave as an artificial cell/nanochromatograph (AC/NC) towards a wide range of (counter-)cations, e.g., ammonium, sodium, rubidium. caesium, calcium, cadmium, nickel. cerium and praseodymium. After formal identification of eight related basic molecular processes, their interplay is categorized tentatively with reference to three parameters: the structure of the respective molecular holes/pores exposed to the solution. the size/ionic radii of the (counter-)cations of the AC/NC, and the lability of the cations' water hydration shell. It is proposed that there is the option to use the AC/NCs to study, e.g., the complexation behaviour of cations under confined conditions with the possibility to mimic cation transport through biological ion channels, but also to get general information about transport processes through molecular pores. The intrinsic properties of the AC/NCs, which can be even synthesized on a (kilo)gram scale. are also thought to open a new era in the study of water structures that may be formed at the nanometre scale in the presence or absence of electrolytes

Structure of a cavity-encapsulated nanodrop of water

Müller A, Bögge H, Diemann E. Structure of a cavity-encapsulated nanodrop of water. INORGANIC CHEMISTRY COMMUNICATIONS. 2003;6(1):52-53.A (H2O)(100) nanodrop of water was found in the cavity of a spherical polyoxomolybdate cluster of the type {(Mo)Mo-5}(12) (spacer)(30) and structurally characterised. The molecules within the water cluster are arranged in three concentric shells with radii of 3.84-4.04, 6.51-6.83 and 7.56-7.88 Angstrom spanned by 20, 20, and 60 molecules, respectively. The first shell dodecahedron is formed exclusively by 20 hydrogen bonds (O...O 2.77-2.92 Angstrom) in the centre and 12 (H2O)(5) pentagons (O...O = 2.66-2.81 Angstrom) formed by hydrogen bonds at the periphery, i.e., the third shell. Each of the H2O molecules of the second (dodecahedral) shell connects the molecules from three different pentagons of the third shell with one molecule of the central dodecahedron.
