Yes to add to Kimberley's answer it is in general true for all the 5d metal complexes as these are kinetically inert compared to 4d metal complexes. This is the reason that most of the catalysts are made from 4d metals and to follow the detailed chemistry of intermediate stages people use 5d to get stable entity to analyze.
Whilst both are d8 systems which means that their electronic configuration for square planar complexes is essentially the same (no unpaired electrons), the energy gap between orbitals for Pt is much larger, as it is one row further down on the periodic table. Therefore, the energy required to break a bond is much greater, making Pt quite stable.
