Reaction of Ni2+ with dimethylglyoxime reagent:
- In basic medium, Ni2+ ions react with dimethylglyoxime reagent to form a complex.
- The reaction results in the formation of a cherry-red precipitate of nickel(II) dimethylglyoximate.

Structure of the product:
- Two dimethylglyoximate units are bound to one Ni2+ ion in the complex.
- Each dimethylglyoximate unit forms a six-membered chelate ring with the Ni2+ ion.

Characteristics of the complex:
- In the complex, two dimethylglyoximate units are hydrogen bonded to each other.
- This complex formation is utilized in analytical chemistry to estimate the amount of Ni2+ ions present in a solution.

Therefore, the correct statements about the reaction and the product are:
- In ammoniacal solution, Ni2+ salts give a cherry-red precipitate of nickel(II) dimethylglyoximate.
- Two dimethylglyoximate units are bound to one Ni2+ ion.
- In the complex, two dimethylglyoximate units are hydrogen bonded to each other.
