Transition Metal Long Sleeve T-Shirts

Os is the periodic table element symbol for the transition metal osmium.

Re is the periodic table element symbol for the transition metal rhenium.

V is for vanadium, one of the transition metals on the periodic table.

Fe is the element symbol for iron on the periodic table. All of the transition metals in this series are yellow. If there's a different color you like, please let me know.

Co is the element symbol for the transition metal cobalt on the periodic table.

Cobalt stannate, more accurately known as cobalt tin trioxide, is the major component of the wonderful cerulean blue! Stannate, which describes any compound with tin (derived from the Latin 'stannum'), is shorter and more convenient.

The cobalt cations associate with the negatively-charged oxygen on the phosphates, just having some good old-fashioned fun. One of the cobalts isn't as keen as the rest, they're off doing their own thing.

Phthalocyanine blue, also known as phthalo blue, is a synthetic dye comprised of the macrocyclic tetradentate phthalocyanine ligand, and a copper metal centre. An oxidation state of 2 for the copper centre is what gives the compound its unmistakable blue hue!

Prussian blue is famous not so much for its stunning colour, but instead for the octahedral geometry of six cyanide ligands around an iron centre within the coordination complex! The complex typically forms a red compound with potassium as the counter ion; to produce the Prussian blue and the observed compound above, potassium hexacyanoferrate is reacted with iron.

Viridian green is a surprisingly simple molecule, but features an organic chemist's favourite bond - hydrogen bonding! Its hydrogens interact with the central oxygen of the chromium (III) oxide.

Y is the periodic table element symbol for the transition metal yttrium.
