What is the hybridization of [PdCl4]2- and [NiCl4]2-?

@ kirti 
in Nicl4 the central atom ni , whoose valence shell configuration in free state is 3d8,4s0, 4p0 . 
as cl are weak ligand , and arrengement of eight 3d electron in ni 2+ ion and in (nicl4)2- 
ion will remain same . thus , it have SP3 hybridisation which have tetradehdral geometry . and are paramagnetic in nature , 
while in the case of (PDCL4) 2- IT WILL BE dsp2 hybridisation , and the structure is
square bipyramidal . 
HOPE IT CLEARS YOUR DOUBT 
ALL THE BEST ..
