What color is Cyclopentadienyl nickel nitrosyl?
Cyclopentadienyl nickel nitrosyl Cyclopentadienyl nickel nitrosyl is a blood-red color liquid. It was discovered by a team at The International Nickel Company. The molecular formula is (CH)NiNO. It can be prepared by treating nickelocene with nitric acid. It is extremely toxic (T+).
Cyanogen Cyanogen is the chemical compound with the formula (CN). It is a colorless, toxic gas with a pungent odor. The molecule is a pseudohalogen. Cyanogen molecules consist of two CN groups – analogous to diatomic halogen molecules, such as Cl, but far less oxidizing. The two cyano groups are bonded together at their carbon atoms: N≡C−C≡N, although other isomers have been detected. Certain derivatives of cyanogen are also called "cyanogen" even though they contain only one CN group. For example, cyanogen bromide has the formula NCBr.
