SUMMARY
The spin-only magnetic moment of the complex [Fe(H2O)5NO]^{2+} is determined to be 3.87, indicating the presence of five unpaired electrons. The iron (Fe) is in the +1 oxidation state with an electron configuration of [Ar]3d^64s^1. However, there is confusion regarding the oxidation states, as some sources indicate Fe in the +3 state and NO in the -1 state, which would also suggest five unpaired electrons. This discrepancy highlights the need for updated information, as older textbooks may contain outdated data.
