IUPAC names of four complexes

Short answer

i) sodium trioxalatoaluminate(III), ii) hexaamminecobalt(III) chloride, iii) tetrahydroxoplumbate(II) ion, iv) pentaaquachlorochromium(III) chloride.

Write IUPAC name of the following co-ordination compounds. i) Na₃[Al(C₂O₄)₃] ii) [Co(NH₃)₆]Cl₃ iii) [Pb(OH)₄]²⁻ iv) [Cr(H₂O)₅Cl]Cl₂

i) Na₃[Al(C₂O₄)₃]: sodium trioxalatoaluminate(III) ii) [Co(NH₃)₆]Cl₃: hexaamminecobalt(III) chloride iii) [Pb(OH)₄]²⁻: tetrahydroxoplumbate(II) ion (charge: x + 4(−1) = −2, so x = +2) iv) [Cr(H₂O)₅Cl]Cl₂: pentaaquachlorochromium(III) chloride
