Among the following complexes (K$$ to $$P),$$K3FeCN6K$$,$$CoNH36Cl3L$$,$$Na3Cooxalate3M$$,$$NiH2O6Cl2N$$,$$K2PtCN4O$$, and $$ZnH2O6NO32PThe$$ diamagnetic complexes are:

Infinity Learn · Accepted Answer

[K] : $$K3FeCN6$$: $$Fe3+$$ has $$3d5$$ configuration; $$CN-$$ is strong field ligand and thus four electrons are paired leaving one unpaired electron with $$d2sp3$$ hybridization and thus paramagnetic.[L]: $$CoNH36Cl3$$:$$Co3+$$ has configuration; $$NH3$$ is strong field ligand thus all six electrons are paired with $$d2sp3$$ hybridization and therefore diamagnetic.[M]: $$Na3Coox3$$: $$Co3+$$ has $$3d6$$ configuration: $$C2O42$$− is strong field ligand and thus all the six electrons are paired with $$d2sp3$$ hybridisation and therefore diamagnetic.[N]: $$NiH2O6Cl2$$:$$Ni2+$$ has $$3d8$$ configuration with two unpaired electrons. $$H2O$$ is weak field ligand and thus $$sp3d2$$ hybridisation and paramagnetic.[O]: $$K2PtCN4$$: $$Pt2+$$ has $$3d8$$ configuration; $$CN-$$ is strong field ligand and thus all the eight electrons are paired with $$dsp2$$ hybridisation and therefore diamagnetic. [P]: $$ZnH2O6NO32$$:$$Zn2+$$ has $$3d10$$ configuration and thus all paired showing $$sp3d2$$ hybridization and so diamagnetic.
