When the coordination compound CrCl6HO is mixed with AgNO, 2 moles of AgCl are precipitated per mole of the compound. Write:
i) the structural formula of the complex
ii) the IUPAC name of the complex
i) the structural formula of the complex
ii) the IUPAC name of the complex
Answer: (i) [Cr(H₂O)₅Cl]Cl₂·H₂O. (ii) Pentaaquachloridochromium(III) chloride monohydrate.
Solution
Only 2 of the 3 chlorides precipitate ⇒ one Cl is inside the coordination sphere; with C.N. 6 the sphere holds 5 HO + 1 Cl, the sixth water being lattice water.
