1 Coordination Compounds
Nickel (Z = 28) combines with a uninegative monodentate ligand X - to form a paramagnetic complex [NiX4]2- . The number of unpaired electron(s) in the nickel and geometry of this complex ion are respectively
1) one, tetrahedral 2) two, tetrahedral 3) one, square planar 4) two, square planar
SOLUTIONS
Hence Nickel has 2 unpaired electrons and the geometry of the complex [Ni X4 ]2- is tetrahedral due to SP3 hybridization.
