Trimetallic Cubane-Type Clusters: Transition-Metal Variation as a Probe of the Roots of Hypoelectronic Metallaheteroboranes

“…34 The Ta-O bond length is slightly longer as compared to the M-O bond lengths observed in other adamantane-like inorganic compounds. 38,41,42 As shown in Table 2, a series of adamantane-like inorganic compounds of various transition metals, (such as, Cu, [34][35][36][37] Mg, 38 Pb, 39 Cr 40 and Mn 41 ) are known and several of them are utilized in industrial catalysis to biomedical activity. Apart from the wide range of applications, 10 their fascinating structural and bonding features make these complexes very important.…”

“…Another noticeable feature of 6 is the presence of one μ 4 -oxo moiety inside the adamantane core . It is an example of an inverse coordination complex, where nonmetal oxygen is surrounded by four tantalum metals in a tetrahedral fashion. − Inverse coordination compounds have noteworthy applications, such as hydrogen gas storage, precursors for novel materials for catalysis, and radioactive protective agents . The Ta–O bond length is slightly longer as compared to the M–O bond lengths observed in other adamantane-like inorganic compounds. ,, …”

Dimers of oxocentred [OCu4]6+ tetrahedra in two novel copper selenite chlorides, K[Cu3O](SeO3)2Cl and Na2[Cu7O2] (SeO3)4Cl4, and related minerals and inorganic compounds

“…THE crystal chemistry of selenium-containing natural and synthetic oxocompounds of copper is of special interest owing to the specific structural features of both Cu 2+ and Se 4+ ions. Cu 2+ may possess different and flexible coordination geometries (Burns and Hawthorne, 1995a,b;Rosner et al, 2007;Melník et al, 2011;Burrows et al, 2012;Krivovichev et al, 2012), while Se 4+ cations form asymmetric (SeO 3 ) 2groups due to the stereochemically active behaviour of the s 2 lone electron pairs, resulting in structurally complex architectures and interesting physical properties (Mao et al, 2008;Zhang et al, 2010;Berdonosov et al, 2013).…”
