  • Alum - potassium aluminum sulfate dodecahydrate (WSHS) Alum - potassium aluminum sulfate dodecahydrate (WSHS) This sample was prepared by the students in the AP Chemistry class at Westerville South High School. Cick on the image itself for an interactive version of the structure (requires Java).
  • 2,5-Dimethyl-1,3-dinitrobenzene (Heather Crather) 2,5-Dimethyl-1,3-dinitrobenzene (Heather Crather) This sample was prepared as part of a qualitative organic lab exercise in Spring 2011. The nitro groups on the benzene ring form weak hydrogen bonds with the aromatic C-H groups. The structure has recently been published: Acta Cryst. (2011). E67, o2276-o2277.
  • 4-Nitro-<i>N</i>-(3-nitrophenyl)benzamide (Colin Taylor) 4-Nitro-N-(3-nitrophenyl)benzamide (Colin Taylor) This material was also prepared as a derivative of 4-nitroanaline for the qualitative organic laboratory. Even though the molecule is not chiral, the twist between the two rings allows it to form intermolecular helices and crystallize in a chiral space group. The structure has also been recently published: Acta Cryst. (2011). E67, o2735.
  • Tris(3-nitro-acetylacetonato)cobalt(III) (Jack Brangham, Chris Rapp) This complex was prepared as part of an independent synthesis project in the Inorganic Chemistry laboratory using a procedure from Inorganic Syntheses (Collman, J. P.; Young, W. L., III; Kauffman, G. B. Inorg. Synth., 1963, 7, 205-207). The structure has recently been published: Acta Cryst. (2012). E68, m312-m313. Tris(3-nitro-acetylacetonato)cobalt(III) (Jack Brangham, Chris Rapp)
  • (C<sub>12</sub>H<sub>18</sub>N<sub>2</sub>)[Mo<sub>6</sub>Cl<sub>14</sub>]·1.5 C<sub>3</sub>H<sub>6</sub>O (Anthony Maldonado and Harsharn Kaur) This compound was accidentally prepared while attempting to isolate the p-phenylenediammmonium salt of the [Mo6Cl14]2- cluster unit in the inorganic laboratory. The acetone solvent underwent a Schiff-base condensation and produced this unusual salt. The anionic cluster unit, the cation, and one of the acetone solvate molecules all sit on inversion centers. (C12H18N2)[Mo6Cl14]·1.5 C3H6O (Anthony Maldonado and Harsharn Kaur)
