wen NH3 acts as ligand doesn’t it form inner orbital complex? what is the hybridisation of [Ni(NH3)6]+2

NH3 IS A WEAK LIGAND  SO IT UNDERGOES OUTER ORBITAL COMPLEX INSTEAD OF INNER ORBITAL COMPLEX .IN NH3 IS A WEAK LIGAND  IT UNDERGOES OUTER ORBITAL COMPLEX and forms octahedral complex with sp3d2 hybrisation and due to presence of two unpaired electrons it exhibits paramagnetism[Ni(NH3)6]+2 Ni oxidation state is +2 as

NH3 is placed on d right side of  d spectrochemical series which means its a strong field ligand
