Double cage

Inorganic salts often do not require fine pulverizing, but they frequently oecome lumpy. In such cases, they are passed mrough a double-cage mill or some type of hammer miU.

Fig. IS. Two of the possible Si, A1 ordering schemes for zeolite X with Si/Al = 1.18. The ratio of intensities Si(4AI) Si(3AI) Si(2Al) Si(lAI) Si(0Al) corresponding to each scheme is given in the upper right-hand corner. is the calculated electrostatic energy for the double cage in units of (qe)2/a, where a is the T—O—T distance. The asterisk denotes the scheme preferred by the authors of ref. 58 from which the figure is taken / 0 denotes the net dipole moment in a double sodalite cage.

C2)2 Agi6. This double cage (435), formed from two edge-sharing C2 Ag9 square antiprisms of which the top faces are capped by the ninth Ag atom, is found in Ag2C2 9Ag(pfp) 3MeCN H20.592 In each, the C2 is bonded to all nine Ag atoms [Ag-C 2.167-2.596(8) A],... 

IX.C. Further examples of C2 Agra clusters were found in complexes obtained from Ag2C2 and Ag(tfa) and various /V-donor ligands,640 Ag(tfa) or Ag(OTf) with (4-hydroxymethyl)pyridine,641 Ag(tfa) or Ag(pfp) with crown ethers,642 and an anionic Ag(I) double cage formed from Ag(tfa), AgN03 and [NMe3(CH2Ph)] +. 643... 

Synthesis of 0-Bonded Derivatives of closo-Dodecaborate Anion. [B12]-[C2B10] Double Cage Boron Compounds - A New Approach to Synthesis of BNCT Agents... 

Here we describe two different approaches to the synthesis of 0-bonded functional derivatives of the c/oso-dodecaborate anion as well as the synthesis of the first [B,2]-[C2Bio] double-cage boron compounds.
