The atomic no of Cobalt is 27 which is intermediate of 18 for noble gas Argon and 36 for noble gas Krypton, practically Cobalt can't accept 9 electrons similarly can not donate nine electrons so it tends to reach the electronic configuration of Krypton by forming extra coordinate covalent bond.
The noble gas configuration for manganese (Mn) is [Ar] 3d5 4s2. This means that it has the same electron configuration as argon (Ar) with 18 electrons, followed by 3d5 and 4s2 orbitals filled with electrons.
