What is the IUPAC name of [Co((NH3)2sar]Cl5?<\/p>\n\n\n\n

The correct answer and explanation is:<\/mark><\/strong><\/p>\n\n\n\n

The IUPAC name of the compound [Co((NH3)2sar)]Cl5 is diamminesarconate(III) chloride pentachloride<\/strong>.<\/p>\n\n\n\n

Explanation:<\/strong><\/p>\n\n\n\n

    \n
  1. Complex Identification:<\/strong>\n
      \n
    • The central metal ion is cobalt (Co), which has an oxidation state of +3 as indicated by the complex’s charge balance. In this complex, cobalt is coordinated to two ammonia (NH3) ligands and one sar (sarconate) ligand.<\/li>\n\n\n\n
    • The ammonia (NH3) ligands are neutral molecules and are called ammine<\/em> in the IUPAC nomenclature.<\/li>\n\n\n\n
    • The sarconate ligand (usually abbreviated as sar<\/em>) is a bidentate ligand. It forms two bonds with the central metal ion.<\/li>\n\n\n\n
    • The remaining part of the complex includes chloride ions, which are present as counterions outside the coordination sphere of the cobalt.<\/li>\n<\/ul>\n<\/li>\n\n\n\n
    • Ligand Naming:<\/strong>\n
        \n
      • Ammine<\/em> is used to describe ammonia ligands.<\/li>\n\n\n\n
      • The sar<\/em> ligand is named sarconate, representing a bidentate ligand that attaches to the metal via two donor atoms.<\/li>\n<\/ul>\n<\/li>\n\n\n\n
      • Coordination Number:<\/strong>\n
          \n
        • The cobalt ion is surrounded by five ligands (two ammine ligands and one sarconate ligand, along with five chloride ions).<\/li>\n\n\n\n
        • The chloride ions are considered counterions<\/em> and do not participate in the coordination with the central metal.<\/li>\n<\/ul>\n<\/li>\n\n\n\n
        • Oxidation State of Metal:<\/strong>\n
            \n
          • The cobalt ion has an oxidation state of +3, which is indicated by the “(III)” suffix.<\/li>\n<\/ul>\n<\/li>\n\n\n\n
          • Complex Charge:<\/strong>\n
              \n
            • The complex has a positive charge of +1 because the total charge from the ligands is neutral, and the chloride counterions balance this by being negatively charged.<\/li>\n<\/ul>\n<\/li>\n<\/ol>\n\n\n\n

              Thus, the full IUPAC name reflects both the identity of the ligands and the overall charge and structure of the complex, leading to the name diammine sarconate(III) chloride pentachloride<\/strong>.<\/p>\n","protected":false},"excerpt":{"rendered":"
