Description

This entry presents Hexane (C6H14; CAS 110-54-3; PubChem CID 8058 (https://pubchem.ncbi.nlm.nih.gov/compound/8058)) as a 3D-printable ball-and-stick model in which every atom carries its engraved element symbol (C, H), 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. Unlike 3DPX-009891 (https://3d.nih.gov/entries/3DPX-009891), this model is engraved for colour-independent reading in the classroom. Biological relevance: Hexane, a simple open-chain alkane, is recorded as a male reproductive toxicant (source: Wikidata Q150440 (https://www.wikidata.org/wiki/Q150440), retrieved 2026-10-10). Structure at a glance 20 atoms: 6 C, 14 H 19 bonds, all single No rings (open-chain structure) No hydrogen-bond donors or acceptors (computed) Every carbon atom is sp3-hybridised (tetrahedral) Use in teaching Counting task: students tally the engraved symbols (6 C, 14 H; 20 atoms) and rebuild the formula C6H14 from the model alone. Geometry: every carbon is sp3-hybridised, so students can check tetrahedral bond angles at any carbon. File and printing STL mesh of 210,644 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: 6.841 × 6.599 × 3.57 Å; at scale factor 10 (1 Å to 10 mm, file read in millimetres) the print measures about 68.4 × 66.0 × 35.7 mm.
