Lec 14 Crystal System ,Void, Magnetic Properties 12th, Chemistry

There are 14 crystal systems.

In the complex ion ML_6^(n+) , M^(n+) has five d-electrons and L is a weak field ligand. According to crystal field theory, the magnetic properties of the complex ion correspond to how many unpaired electrons?

Crystal field theory was proposed by H.beths (1929) and Van Vleck (1932) and as originally applied to ionic crystals to explain their optical properties and is, therefore, called crystal field theory, however, this theory was applied to the study of coordination compounds in 1950 and this theory accounts for more satisfactory expalnation for the properties of complexes especially colour and magnetism. What is the hybridisation of [Ni(H_(2)O)_(6)]^(2+) ?
