Dimethylglyoxime is a chemical compound described by the formula CH 3 CNOHCNOHCH abbreviation is dmgH 2 for neutral form and dmgH for anionic form where H stands for hydrogen This colourless solid is the dioxime derivative of the diketone butane23dione also known as diacetylDmgH 2 is used in the analysis of palladium or coordination complexes are of theoreticalFurther Details
The dimethylglyoxime test for detection of nickel first described by Fleigl 1 and modified by Fisher 2 consists of adding a few drops of 1 dimethylglyoxime in alcoholic solution and a few drops of 10 ammonium hydroxide solution to a test object and observing for the presence of a red precipitate In our modification of this procedure a fewFurther Details
The vicdioxime chelates of nickel and palladium have been shown to be diamagnetic by several workers 275412 Willis and Mellor 86 have shown that the magnetic moment of nickel methylglyoxime rises to 15 BM in pyridine solution which indicates an Increase in the coordination number of nickelFurther Details

Nickel is a silverywhite metal with a slight golden tinge that takes a high polish It is one of only four elements that are magnetic at or near room temperature the others being iron cobalt and Curie temperature is 355 °C 671 °F meaning that bulk nickel is nonmagnetic above this temperature The unit cell of nickel is a facecentered cube with the lattice parameter ofFurther Details
