Thiacloprid 3D Molecular Model — CAS 111988-49-9

Thiacloprid (C10H9ClN4S, CAS 111988-49-9) — a free educational 3D molecular model for teachers and students, by MolGod.org. Systematic name: (3-((6-Chloropyridin-3-yl)methyl)-1,3-thiazolidin-2-ylidene)cyanamide. Every sphere shows which element it is through an engraved symbol, not a colour code.

In Thiacloprid the ring system sets the overall shape: two rings (one 5-membered and one 6-membered), one of them aromatic. Altogether 26 bonds hold the model together (18 single, 1 double, 1 triple and 6 aromatic). Quick starter: ask students to count the engraved symbols (10 C + 9 H + 1 Cl + 4 N + 1 S) and check that they add up to 25 atoms and the formula C10H9ClN4S. Its closest structural relative in the MolGod.org collection is (6-Chloropyridin-3-yl)methanol (CAS 21543-49-7); printing them side by side makes a quick compare-and-contrast exercise. Spot-the-group challenge: can students find the thioether linkage (C-S-C), the nitrile (cyano) group (-C#N), the pyridine-type ring nitrogen and the C-Cl bond? It makes aromaticity and delocalised electrons, heteroaromatic rings (nitrogen inside an aromatic ring), as well as organohalogen compounds and carbon-halogen bonds easier to see.

Teachers and students can use this MolGod.org model free of charge. Teachers: hand out printed copies and ask students to rebuild the structural formula from the model.

A ball-and-stick model of Thiacloprid 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: 339,256 triangles, closed (watertight) single solid. Coordinates in ångström (STL stores no unit) — scale the model deliberately in your slicer.
