For #"pentamminechlorochromium(III+) nitrate"#...can you...?
#"a. Give the d-electron count at the transition metal centre."#
#"b. Predict the spin state of the d-electrons."#
#"c. Identify the outer sphere ions?"#
#"d. Predict whether the complex is paramagnetic,"#
#"e. Give a possible coordination sphere isomer."#
We start with a
a. The transition metal ion
c. The outer sphere ligands are reasonably the nitrate counter ions; as written the nitrates are not coordinated to the metal.
d. The complex is certainly a paramagnet. How do I know this?
e. For a coordination sphere isomer, simply replace one of the octahedrally coordinate ligands (ammine or chloro) with the counter ion, nitrato: i.e.
