. Write the name the structure and the magnetic behaviour of each one of the following complexes


Write the name, the structure and the magnetic behaviour of each one of the following complexes

(i) [Pt(NH3 )Cl(NO2 )]

(ii) [Co(NH3 )4Cl2 ]Cl

(iii) Ni(CO)4

(At. nos. Co = 27, Ni = 28, Pt = 78)

Best Answer

(i) [Pt(NH3 )2ClNO2 ]: Diamminechloridonitrito-N-platinum (II); Pt2+ = 5d 8

hybrid

      Structure = Square planar; Magnetic behaviour : Diamagnetic

(ii) [CO(NH3 )4Cl2 ]Cl: Tetraamminedichloridocobalt (III) chloride; Co3+ = 3d6

hybrid

          Structure = Octahedral; Magnetic behaviour : Diamagnetic

(iii) Ni(CO)4 : Tetracrabonyl nickel(o); Ni = 3d8 4s2

sp3 hybrid

            Structure = Tetrahedral; Magnetic behaviour : Diamagnetic
