THE CRYSTAL STRUCTURE OF STURMANITE [PDF]
The Canadian Mineralogist, 2004 Sturmanite, ideally Ca6Fe 3+ 2(SO4)2.5[B(OH)4](OH)12•25H2O, is trigonal, P31c, Z = 2, with a 11.188(9), c 21.91(7) A, V 2375.1(5) A 3 . The crystal structure has been refined to an R index of 0.079. As in the case of ettringite, two coaxial elements parallel to [001] can be considered as the most distinctive features of sturmanite.

Crystal structure of ruthenocenecarbonitrile [PDF]
Acta Crystallographica Section E Crystallographic Communications, 2015 The molecular structure of ruthenocenecarbonitrile, [Ru(η5-C5H4C[triple-bond]N)(η5-C5H5)], exhibits point group symmetrym, with the mirror plane bisecting the molecule through the C[triple-bond]N substituent. The RuIIatom is slightly shifted from the η5-C5H4centroid towards the C[triple-bond]N substituent.
