ANSWER PLZ.....
the colour of coordination compound bisdimethylglyoxime nickle ( 1 1 ) is :

Answer 1

bright red
Dimethylglyoxime is used to detect and quantify nickel, which forms thebright red complex nickel bis(dimethylglyoximate) (Ni(dmgH)2).

Answer 2

Because the distance in orbital splitting varies with ligand strength, a coordination complex with the same metal center can have a variety of colors based upon the coordinating ligand. For example, an aqueous solution of Ni(H2O)62+ has a light green color, but Ni(NH3)62+ is deep blue. The color arises from the change in energy between the t2g-eg orbitals. NH3 is a stronger field ligand, which pushes the orbitals further apart from one another as well as displaces the H2O ligands from the metal center. We will further explore the effect of ligands on color and coordination complexes in this experiment.
so , the colour is blue.
