Here's the MSDS from Matheson TriGas: http://www.mathesontrigas.com/pdfs/msds/MAT16290.pdf As an organometallic chemist, I used to mention this particular compound in my lectures. The vapor density of Ni(CO)4 is approximately 6 (air = 1). So even with a good fume hood, the vapors can pool in the floor of the hood and flow onto the floor. I once saw an MSDS that said the best way to work with it was in an open field and to stand upwind. If you're using it in a flow system inside a hood, the protocol should employ some sort of scrubber on the system outlet. Ni(CO)4 reacts with phosphines to yield (non-volatile) nickel complexes of the formula Ni(CO)4-x(L)x where L = the phosphine ligand. These are classic reactions in Inorganic chemistry and much information can be found in the literature. Thermal decomposition is also a good way to decompose this material (it falls apart around 200 C). Any number of papers that have used Ni(CO)4 over the years probably describe their scrubber systems. Send your researcher off to his computer terminal or the library to look them up. As a total aside, nickel tetracarbonyl was discovered by Mond in 1899. It was reported to have a "musty odor". We organometallic chemists like to joke that Mond managed to scrawl "musty odoo" in his lab notebook before collapsing dead, but in actuality he died in 1909 at the age of 70: http://en.wikipedia.org/wiki/Ludwig_Mond Regards, Rob Toreki -- ===================================================== Safety Emporium - Lab & Safety Supplies featuring brand names you know and trust.
