Answer 2

Structure of Tetracyanonickelate (II) ion:

First of all, the central metal is $Ni^{+2}$, as it is mentioned Ni (II) :

CN- is a strong field $liga{n}d$, so electronic configuration of Ni(+2) in presence of CN-

${Ni}^{ + 2} : (Ar) \: 3 {d}^{8}$

$\implies {Ni}^{ + 2} : (Ar) \: \boxed{ \uparrow \downarrow } \: \boxed{ \uparrow \downarrow| \uparrow \downarrow | \uparrow \downarrow| - | - } \: \boxed{ - } \: \boxed{ - | - | - }$

So, electrons from CN- will be inserted into 3d, 4s, and 4p orbital.

So, hybridisation will be : d²sp.

HENCE, STRUCTURE WILL BE TETRAHEDRAL.
