The black precipitate of nickel sulphide dissolves in aqua regia  and the reaction takes place as follows:
$3NiS+2HN{O}_3+6HCl\stackrel{ }{\to }3NiC{l}_2+2NO+3S+4H_{2}O$
After treatment with aqua regia nickel-chloride is obtained which is soluble in water. when dimethyl glyoxime is added to the aqueous solution of nickel chloride, made alkaline, by adding $N{H}_{4}OH$  solution, a brilliant red precipitate is obtained. Find sum of the number of  $Ni-N$ linkages and  $Ni-C$linkages in brilliant red precipitate.
