Description

This entry presents Triglycidyl isocyanurate (C12H15N3O6; CAS 2451-62-9; PubChem CID 17142 (https://pubchem.ncbi.nlm.nih.gov/compound/17142)) as a 3D-printable ball-and-stick model in which every atom carries its engraved element symbol (C, H, N, O), so the model can be read without a colour key. Atomic coordinates come from the PubChem-computed 3D conformer (not an experimental crystal structure); coordinates and connectivity are unchanged. Structure at a glance 36 atoms: 12 C, 15 H, 3 N, 6 O 39 bonds: 36 single, 3 double Four rings (three 3-membered and one 6-membered) Functional groups: one isocyanurate ring (six-membered ring of alternating N atoms and C=O groups) and three epoxide rings (three-membered C-O-C ring) Three stereocentres; configuration not defined in the source record (no R/S label) — IUPAC name 1,3,5-tris(oxiran-2-ylmethyl)-1,3,5-triazinane-2,4,6-trione No hydrogen-bond donors and six acceptors (computed) Fraction of sp3-hybridised (tetrahedral) carbon atoms: 0.75 (computed) Use in teaching Counting task: students tally the engraved symbols (12 C, 15 H, 3 N, 6 O; 36 atoms) and rebuild the formula C12H15N3O6 from the model alone. Stereochemistry: locate the three stereocentres; the source record defines no configuration, so the printed conformer should not be read as a specific stereoisomer. Functional groups: find the isocyanurate ring (six-membered ring of alternating N atoms and C=O groups) and the three epoxide rings (three-membered C-O-C ring) on the model and name each one. File and printing STL mesh of 465,186 triangles, a closed (watertight) single solid. Coordinates are in ångström and STL stores no unit, so scale the model deliberately in your slicer. Measured bounding box: 8.947 × 9.078 × 9.896 Å; at scale factor 10 (1 Å to 10 mm, file read in millimetres) the print measures about 89.5 × 90.8 × 99.0 mm.
