Write the coordination number and oxidation state of Platinum in the complex [Pt(en)2Cl2]

The coordination number of Platinum in the complex [Pt(en)2Cl2] is 6. Platinum atom is surrounded by six donor atoms. Chlorine is a monodentate ligand with one donor atom. Ethylene diamine (en, H2N−CH2−CH2−NH2) is a bidentate ligand with 2 donor N atoms.
Let x be the oxidation state of Platinum in the complex [Pt(en)2Cl2]. The oxidation states of Cl and en are 0 and 0 respectively.
x + 2(0) + 2(0) = 0
x = +2
The oxidation state of Platinum in the complex [Pt(en)2Cl2] is +2.
