Nickel bis(dimethylglyoximate) is the coordination complex with the formula Ni[ONC(CH3)C(CH3)NOH]2. The compound is a bright red solid. It achieved prominence for its use in the qualitative analysis of nickel.[1]
Structure[edit]
Nickel(II) is square planar.[2] It is surrounded by two equivalents of the conjugate base (dmgH−) of dimethylglyoxime (dmgH2). The pair of organic ligands are joined through hydrogen bonds to give a macrocyclic ligand. The complex is distinctively colored and insoluble leading to its use as a chelating agent in the gravimetric analysis of nickel.
How to package a dmg file. The use of dimethylglyoxime as a reagent to detect nickel was reported by L. A. Chugaev in 1905.[3]
Not because she's not 'OP', but because getting caught means you're basically dead, barring a good save by your support.

Ni Dmg 2 2 Nomenclature List
We did a gravimetric analysis lab and I have masses for the DMG-Ni complexes that we recovered but I need to find the percent nickel in each sample.Relevant Equations: I believe you take the mass of the DMG-Ni complex sample and multiply that by the mass ratio of Ni2+ over the FW of DMG. Then divide the result by the mass of the sample and multiply by 100%.
