Solution:


In all the complexes, the oxidation state of central metal ion is . Any complex with molecular formula shows geometrical isomerism. Moreover, valence shell electron configuration of in and in (all are attached to weak field ligands) suggest that there are unpaired electrons (paramagnetic) whereas do not have any unpaired electrons, hence, it is diamagnetic.
