The IUPAC name of the compound [Cr(NH3)5(NCS)][ZnCI4] isa)pentammine i...
The given compound is [Cr(NH3)5(NCS)][ZnCI4], which is a coordination compound.
IUPAC name of the compound:
To name the given compound, we need to identify the central metal ion and the ligands attached to it.
Central metal ion: The compound contains two metal ions, chromium (Cr) and zinc (Zn).
Ligands: The compound contains two types of ligands, NH3 and NCS-. NH3 is a neutral ligand and NCS- is a negatively charged ligand.
Naming of the complex ion containing chromium (Cr):
Step 1: First, we need to name the complex ion containing chromium. The chromium ion has a coordination number of six, and the ligands attached to it are five NH3 and one NCS-. To name the complex ion, we follow the following steps:
a) Write the name of the metal ion: chromium
b) Write the name of the ligands attached to it: pentammine (NH3) and isothiocyanato (NCS-)
c) Write the oxidation state of the metal ion: chromium (III)
d) Write the charge of the complex ion: Since NH3 is a neutral ligand and NCS- is a negatively charged ligand, the charge on the complex ion is -1.
Therefore, the name of the complex ion containing chromium is pentammine isothiocyanatochromium (III).
Naming of the complex ion containing zinc (Zn):
Step 2: Next, we need to name the complex ion containing zinc. The zinc ion has a coordination number of four, and the ligands attached to it are four Cl-. To name the complex ion, we follow the following steps:
a) Write the name of the metal ion: zinc
b) Write the name of the ligands attached to it: tetrachloro (Cl-)
c) Write the oxidation state of the metal ion: zinc (II)
d) Write the charge of the complex ion: Since Cl- is a negatively charged ligand, the charge on the complex ion is -2.
Therefore, the name of the complex ion containing zinc is tetrachlorozincate (II).
Overall naming of the compound:
Step 3: Finally, we can combine the names of the two complex ions to name the overall compound. Since the complex ion containing chromium has a negative charge and the complex ion containing zinc has a positive charge, they combine to form an ionic compound with the formula [Cr(NH3)5(NCS)][ZnCI4].
Therefore, the IUPAC name of the compound [Cr(NH3)5(NCS)][ZnCI4] is pentammine isothiocyanatochromium (III) tetrachlorozincate (II).
