Tris(2,4-di-tert-butylphenyl) phosphite

Tris(2,4-di-tert-butylphenyl) phosphite (C42H63O3P, CAS 31570-04-4) — a free educational 3D molecular model for teachers and students, by MolGod.org. Every atom carries its engraved element symbol (C, H, O, N...), so no colour key is needed.

Look at the skeleton first: Tris(2,4-di-tert-butylphenyl) phosphite contains three 6-membered rings, all of them aromatic, and students can trace 111 bonds (93 single and 18 aromatic). Quick starter: ask students to count the engraved symbols (42 C + 63 H + 3 O + 1 P) and check that they add up to 109 atoms and the formula C42H63O3P. On the printed model, students can point to the phosphite ester group (P(O-C)3). A good fit for lessons on aromaticity and delocalised electrons. Want a comparison? The most similar structure in the MolGod.org collection is Phenol, 4-(1,1-dimethylethyl)-2-nitro- (CAS 3279-07-0).

Free for education: MolGod.org publishes engraved molecular models for teachers, students and schools. Teachers: use it as a hands-on starter before drawing the structural formula on the board.

A ball-and-stick model of Tris(2,4-di-tert-butylphenyl) phosphite with each element symbol recessed into its atom sphere, generated by MolGod.org from a PubChem-computed 3D conformer (not an experimental crystal structure); atomic coordinates and connectivity are unchanged. STL mesh: 1,274,198 triangles, closed (watertight) single solid. Coordinates in ångström (STL stores no unit) — scale the model deliberately in your slicer.
