Cover illustration: An Exact Quasi-Ferrodistortive Ordering in (N,N'-Di-n-butylthiourea-S)(N-salicylideneglycinato-O,N,O')copper(II), see Warda, pages 460-462. Displacement ellipsoids are shown at the 40% probability level for non-H atoms.
cif-access (inorganic compounds)
The [Cu4I6]2− ion in this compound has twofold rotation symmetry while the seven-coordinate K+ ion has a geometry midway between capped octahedral and end-capped trigonal prismatic.
cif-access (organic compounds)
1,6-Bis(triphenylphosphino)-closo-decaborane is substituted at an apical and an equatorial position of the closo-decaborane framework by triphenylphosphine groups with B-P bond lengths of 1.879 (6) and 1.925 (6) Å.
Cycloaddition of (Z)-1,1,2,5,5,5-hexafluoro-4-phenyl-3-trifluoromethyl-1,3-pentadiene with pyridine gave the (1S,9aR) racemate as the major product and the (1S,9aS) racemate as the minor product, as determined by the crystal structures of the title compounds.
inorganic compounds
The structure of α-(AlMnSi) is reproduced by the connection of two large atom clusters with icosahedral symmetry (a Mackay icosahedron and a double-Mackay icosahedron). Si and Mn atoms are proposed to constitute icosahedral arrangements in the atom clusters.
