What’s on the Complex Ions poster
A 4-row table: Coordination · Shape · Example.
Coordination number determines shape.
- 6 — Octahedral — [Cu(H₂O)₆]²⁺
- 4 — Tetrahedral — [CuCl₄]²⁻
- 4 — Square planar — [Pt(NH₃)₂Cl₂]
- 2 — Linear — [Ag(NH₃)₂]⁺
Bidentate ligands like ethanedioate occupy two coordination sites. EDTA is hexadentate and occupies all six.
Questions about the Complex Ions poster

- A 4-row table: Coordination · Shape · Example. Coordination number determines shape. 6 — Octahedral — [Cu(H₂O)₆]²⁺; 4 — Tetrahedral — [CuCl₄]²⁻; 4 — Square planar — [Pt(NH₃)₂Cl₂]; 2 — Linear — [Ag(NH₃)₂]⁺.

- Who is the Complex Ions poster for?
- Complex Ions belongs to the Chemistry section rather than to a school year, because physical science is not something one grade owns. Anyone learning inorganic can pin it up — a beginner, a student mid-course, or someone revising years later.
- When should you use the Complex Ions poster?
- A ligand donates a lone pair into a vacant orbital. That is a dative covalent bond. A wall chart earns its place by being glanceable from where the work is happening, so Complex Ions belongs on the wall where that physical science work actually happens, within glancing distance, rather than filed away.
- What other posters go with Complex Ions?
- Catalysts, Electrolysis and Environmental Chemistry sit alongside Complex Ions in the Chemistry section. Printed together they make a wall rather than a single sheet, which is how a reference set actually gets used.CatalystsElectrolysisEnvironmental Chemistry
- Is the Complex Ions poster free to download and print?
- Yes. Complex Ions downloads as a free PDF with no account, no email and no watermark, like everything else in the Chemistry section. Print as many copies as you like for a home, a classroom, a library or a tutoring group; reselling the file is the only thing the licence rules out.Read the licence
- What size does the Complex Ions poster print at?
- Complex Ions is a vector PDF laid out for US Letter, and prints on A4 with Fit to page — the same file, no separate download. Because every mark on it is drawn rather than photographed, it stays sharp enlarged to A3, A2 or A1 at a copy shop. Colour carries emphasis only, so a greyscale print of Complex Ions loses nothing.Printing guide
