Cationic Boron‐Centred Hexanuclear Zirconium Cluster Compounds with Nitrilo Ligands and [MIIICl4]– Counter Ions: [(Zr6B)Cl12(CH3CN)6][MIIICl4] with MIII = Al, Ga, In

“…The average Zr-Zr, ZrCl i , Zr-N and Zr-B distances (see Table 2 [14] The Zr-Zr and Zr-B bond lengths generally depend strongly on the number of cluster-based electrons. [9][10][11]13,14,26] The measured values and also the refined compositions are in good agreement with other known Zr cluster compounds with closed-shell electronic configurations, i.e. 14-cluster-based electrons.…”

“…Initial work in this research area by J. D. Corbett and T. Hughbanks and coworkers has focused on the dissolution process of the solid precursors as well as on elaborating various analytical methods for the characterization of the dissolved cluster species. [9][10][11][12][13]15,18,[23][24][25][26] In the latter case heteroatom NMR spectroscopic techniques have proven very useful. [15,23,28] In order to develop the solution chemistry of Zr cluster compounds further and to ensure high yields of new compounds, a high solubility of the precursor is required.…”

“…[1][2][3][4][5][6][7] The interest in zirconium cluster chemistry has been raised again, when it was discovered that the cluster core remains intact in solution on excision from solid-state compounds. [9][10][11][12][13] Starting from these initial reports a solution chemistry of zirconium cluster compounds emerged, where the original exo-halogenido . [14] An especially interesting group of cluster compounds comprises that with neutral ligands L, because cluster units with a positive charge (depending on the type of interstitial atom) and thereby with Lewis-acidity are accessible.…”

“…Excision reactions tend to be low yielding, and can often benefit from the use of Soxhlet extraction techniques. Only a very few excision reactions have beenreported to succeed in dismantling a 3D cluster-containing framework (143)(144)(145).…”

Mo3S7(dmit)3: from material to models

“…Polymeric clusters were first synthesized in 1978 by John Corbett, who studied their rich and complex chemistry (Corbett (1997)). These materials find vast applications in solution chemistry (Rogel and Corbett (1990)) and act as molecular conductors, semiconductors, supra molecular adducts 1 (Meyer et al (2006)) .…”
