It crystallizes in isometric cubic habit, although octahedral
and more complex isometric forms are not uncommon.
The crystal has an octahedral
shape with small chips on the edges and tops.
The Molymod Shapes of Molecules Model is an educational aid designed for students with learning disabilities to teach them how to create eight models that feature examples of coordination numbers 1 to 6, including linear hydrogen chloride, linear beryllium chloride, bent water, trigonal planar, pyramidal ammonia, tetrahedral methane, trigonal bipyramidal and octahedral
On the basis of electronic spectra and magnetic moment data, an octahedral
geometry was proposed for all synthesized complexes (1-3).
The geometrical embroidery patterns consisted of straight lines and broken lines, zigzags, triangles, quadrangles, six - and octahedral
rosettes, diamonds, stars and the symbolical image of the sun.
The 16-sided structure has an octahedral
roof, with a smaller octahedral
cupola having eight sides with clerestory windows between.
Nevertheless, reflectance also exists in the green region (485-570 nm) albeit in a lower amount, thereby indicating the coexistence of octahedral
and tetrahedral sites in the pigment structure .
The FT-IR spectrum of uncontaminated black cotton soil shows band at 3628 [cm.sup.-1] in -OH stretching region is due to a hydroxyl group bonded with octahedral
([Al.sup.+]) cations (Vicente-Rodriguez et al.
Elements such as Ni, Zn, Cu, and Mn can be substituted at the tetrahedral site and octahedral
site in the [Fe.sub.2][O.sub.4] ferrite .
It has been suggested that Co(III) complexes, with their octahedral
geometries and low-spin [d.sup.6] configurations, may also represent an effective class of prodrugs for the treatment of cancer [2,3,20-23].
