Is cobalt (III) hexaaqua paramagnetic or diamagnetic?
Quoting Housecroft and Sharpe "Inorganic Chemistry" (second edition): "The blue, low-spin $\ce{[Co(H2O)6]^3+}$ ion can be prepared in situ by ...".
Greenwood and Earnshaw says about $\ce {Co}^{3+}$ complexes "these are virtually all low-spin and octahedral" and "Even $\ce{[Co(H2O)6]^3+}$ is low spin".
Thus $\ce{[Co(H2O)6]^3+}$ is $d^6$, octahedral and low spin. It is thus diamagnetic.
