Chemistry of Materials, 2014Co-Authors: Zayd L, Darren W Johnson, Katherine M Wentz, Blake A Hammann, Iya Chang, Maisha K Kamundedevonish, Paul Hayeon Cheong, Victor V Terskikh, Sophia E HayesAbstract:Solid-state 71Ga and 69Ga NMR was used to probe the structure of the hydroxo-aquo Cluster, [Ga13(μ3-OH)6(μ2-OH)18(H2O)24](NO3)15, envisioned as a solution-processable material for thin film electronics. This species, termed Ga13, is made up of three types of 6-coordinate gallium sites, with bridging OH groups and H2O species decorating the outer edges. Solid-state NMR at two magnetic fields (13.9 and 21.1 T) of these quadrupolar nuclei, in conjunction with modeling, demonstrates that these sites are best represented as distorted octahedra, exhibiting a wide range of distinct quadrupolar couplings and asymmetry parameters. This information is critical for analyses of the local coordination environment for gallium in related gallium-oxide films, and this work adds to the growing body of evidence that gallium solid-state NMR is a useful tool for structural analyses.

unravelling the complexities of Inorganic and supramolecular self assembly in solution with electrospray and cryospray mass spectrometry
Chemical Communications, 2009Co-Authors: Haralampos N Miras, Elizabeth F Wilson, Leroy CroninAbstract:Electrospray (ESI) and cryospray mass spectrometry (CSI-MS) are proving to be exceptionally versatile tools when used in conjunction with high resolution time-of-flight (TOF) systems to investigate the self-assembly of supramolecular architectures, Inorganic coordination and organometallic compounds, labile molecules and Clusters both from a structural and mechanistic point of view. In this feature article, we review very recent progress where mass spectrometry is being applied to highly labile and complex coordination and polyoxometalate (POM) Cluster systems and we present some highlights from our initial electrospray and cryospray studies, which probe the self-assembly of Inorganic Cluster architectures. We discuss the major contributions of ESI and CSI-MS to labile and self-assembling Inorganic architectures with great emphasis on future potential and ramifications for Inorganic chemistry and the area of self-assembly as a whole.

probing the self assembly of Inorganic Cluster architectures in solution with cryospray mass spectrometry growth of polyoxomolybdate Clusters and polymers mediated by silver i ions
Journal of the American Chemical Society, 2008Co-Authors: Elizabeth F Wilson, Hamera Abbas, Bridgette J Duncombe, Carsten Streb, Deliang Long, Leroy CroninAbstract:Cryospray mass spectrometry (CSI-MS) has been used to probe the mechanism of self-assembly of polyoxometalate Clusters in solution. By using CSI-MS and electronic absorbance spectroscopy it was possible to monitor in real-time the self-assembly of polymeric chains based on [Ag2Mo8O26]2−n building blocks. The role of the AgI ion in the solution state rearrangement of molybdenum Lindqvist ({Mo6}) into the silver-linked β-octamolybdate ({Mo8}) structure ((n-C4H9)4N)2n[Ag2Mo8O26]n (1) is revealed in unprecedented detail. A monoanionic series, in particular [AgMomO3m+1]− where m = 2 to 4, and series involving mixed oxidation state polyoxomolybdate species, which illustrate the in-solution formation of the (Ag{Mo8}Ag) building blocks, have been observed. CSI-MS detection of species with increasing metal nuclearity concomitant with increasing organic cation contribution supports the hypothesis that the organic cations used in the synthesis play an important structure-directing role in polyoxometalate (POM) growt...
