It is always interesting to see the safe handling procedures for potentially dangerous chemicals. Few will encounter these chemicals, so seeing them, and watching test that show their chemical properties is always interesting. I really appreciate the comments about their smell and weight and any other property that cannot be experienced by just watching the video.

[@russellfranks3811]

Wow. This was very interesting. This brought back a lot of memories from when I used to work with iron pentacarbonyl back in the mid-90s. Iron pentacarbonyl has a very distinct musty odor that always reminded me of a stuffy room that hadn't been opened up in a really long time. Back then, to make iron pentacarbonyl easier to handle, I would either convert it to diiron pentacarbonyl via photolysis in glacial HOAc or I would convert it to triiron dodecacarbonyl by reacting it with triethylamine. That was a long and tedious reaction. The temperature had to be kept within a narrow range for 18 hrs. After purification, the isolated triiron dodecacarbonyl solid would appear almost black, but on closer inspection, the crystals were actually a very dark green color. Thank you for posting this. Best wishes from a reformed organometallic chemist.

[@nerfinator03]

If possible could you say what you used it for?

[@russellfranks3811]

@@nerfinator03 we were interested in synthesizing and studying the reactivity of different pi-bonded organoiron compounds. These compounds typically had coordinated carbonyl groups as well as various hydrocarbon ligands, bonded to the iron via sigma bonds and/or pi bonds. Iron carbonyls were often the starting point for introduction of the iron carbonyl moiety in the structure. The good thing about this type of organometallic compound is that many of them are decently air-stable in the solid state at room temperature. This made handling and manipulation of the compounds much easier, i.e. no need for Schlenk techniques or glove box.

My second Ph.D. research project (the first one was discarded after 4 months) started with converting Fe(CO)5 to the dark green Fe3(CO)12 -- lovely almost-black crystals. That was almost 30 years ago, so I don't recall the details, but I seem to recall that photolysis was one of the steps. The Fe3(CO)12 was then reacted with thiophene (C4H4S) with a reflux/Soxhlet extractor to give a nifty organometallic compound, Fe(C4H4)Fe(CO)3, with a dark-metallic deposit of FeS on the vessel walls. It was one of the smellier projects in the lab, which was already notable for some unpleasant organometallic-related odours. Though the work was done in a fume hood, traces clung to my gloves and the arms of my lab coat. Good times... I really miss doing that stuff. One of my old "magic with chemistry" books described preparing ferrous oxalate, then thermolysing that to give CO2 and what was supposed to be pyrophoric iron. I never had much success with it; the resulting iron never did anything more than smouldering a bit, instead of the expected stream of sparks as it was poured out of the test tube.
