We all have our favorite molecules , here are some of mine .
This wonderfully named mineral is called after the US amateur mineralogist Wilfred R. Welsh. Its formula is Ca2SbMg4FeBe2Si4O20. Some people think it's quite a nice mineral, but others think it's 'well-shite'.
Yes, believe it or not, there is actually a molecule called Arsole... and it's a ring! It is the arsenic equivalent of pyrrole, and although it is rarely found in its pure form, it is occasionally seen as a sidegroup in the form of organic arsolyls. For more information, see the paper with probably the best title of any scientific paper I've ever come across: "Studies on the Chemistry of the Arsoles", G. Markl and H. Hauptmann, J. Organomet. Chem., 248 (1983) 269. Contrary to popular belief, new research (see reference below) shows that arsoles are only moderately aromatic... Incidentally US patent number US 3 412 119 by the Dow Chemical Company is entitled 'Substituted Stannoles, Phospholes, Arsoles, and Stiboles' - I didn't know there was a substitute for an arsole...
Furthermore, the structure where arsole is fused to a benzene ring is called 'benzarsole', and apparently when it's fused to 6 benzenes it would be called 'sexibenzarsole' (although that molecule hasn't been synthesised yet). Another well known poisonous arsenic molecule is the simple hydride, called 'arsine', with formula AsH3.
And on a related theme, I've been told of an Aryl Selenide compound with the superb shorthand of ArSe, which is both toxic and smelly.
Also, the related molecule phosphole (which just replaces As with P) is quite amusing if you are a French speaker, since it's pronounced the same as 'fausse folle' (literally false woman), which means both a 'crazy woman' and a 'drag-queen' or 'ladyboy'.
This is a triterpenoid organic acid that is found in Pistacia resin, and is therefore of interest to people studying archaeological relics, shipwrecks and the contents of ancient Egyptian jars. But why it's called moronic acid is still unknown... Derivatives of this are called moronates.
