Molecular iron maidens' structures are noted for the distinctive ultra-short interactions between the apical hydrogen atom, or its small substituent, and the benzene ring's surface. High steric hindrance is a commonly cited consequence of the forced ultra-short X contact in iron maiden molecules, ...
The geometry ion which hs no d electrons in the central metal atom is : [Atomic number Cr=24,Mn=25,Fe=26,Co=27] A[MnO4]− B[Co(NH3)6]3+ C[Fe(CN)6]3− D[Cr(H2O)6]3+Submit The geometry ion which hs no d electrons in the central metal atom is : [Atomic number Cr=24...

An anion is formed when an electron is added to the valence shell of an atom. The anion has a net negative charge in it. In anion the extra electron added occupies more space and maximizes the shielding. Anions will have larger size compared to cation...
